SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
BASIS OF PRESENTATION	A) BASIS OF PRESENTATION The condensed consolidated balance sheets as of September 30, 2025 and June 30, 2025, the condensed consolidated statements of operations for the three months ended September 30, 2025 and 2024, the condensed consolidated statements of cash flows for the three months ended September 30, 2025 and 2024, and the condensed consolidated statements of stockholders' equity for the three months ended September 30, 2025 and 2024, have been prepared by the Company in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and have not been audited. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for all periods presented have been made. The operating results for any interim period are not necessarily indicative of the operating results that may be experienced for the full fiscal year. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025. The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses. Significant estimates and assumptions are used for, but are not limited to, allowances for credit losses, reserves for excess and obsolete inventories, long-lived and right-of-use assets, income tax valuation allowance, stock-based compensation and deferred compensation. Actual results could differ from the Company's estimates.
INVESTMENTS	B) INVESTMENTS Debt securities are classified as held-to-maturity as the Company has the positive intent and ability to hold them to maturity. The securities are carried at amortized cost as current or noncurrent based upon maturity date and unrealized gains and losses are recognized when realized. The amortized cost of debt securities is adjusted for amortization of premium and accretion of discounts to maturity. Such amortization or accretion is included in interest income, along with other interest income earned on cash and cash equivalents. Accrued interest receivable on held-to-maturity debt securities is shown separately on the condensed consolidated balance sheets and is not included in any estimate for credit losses. No allowance for credit losses on held-to-maturity U.S. Treasury securities is recorded as these securities have the following characteristics that support a zero-loss expectation: they are explicitly guaranteed by the U.S. government, are consistently highly rated by major rating agencies and have a long history of no credit losses. See Note 2 for additional information on investments.
FAIR VALUE MEASUREMENTS	C) FAIR VALUE MEASUREMENTS Cash equivalents, accounts receivable, and accounts payable approximate fair value based on the short maturity of these instruments. The Company’s U.S. treasury debt securities are recorded at amortized cost with fair value disclosure. They have a readily available market price (Level 1 input), thus a lesser degree of judgment needs to be used in measuring fair value, and fair value was determined by quoted market prices. The fair value is based upon quoted market prices and is disclosed in Note 2.
INCOME TAXES	D) INCOME TAXES We estimate a provision for income taxes based on the effective tax rate expected to be applicable for the fiscal year. If the actual results are different from these estimates, adjustments to the effective tax rate may be required in the period such determination is made. Additionally, discrete items are treated separately from the effective rate analysis and are recorded separately as an income tax provision or benefit at the time they are recognized. An income tax provision of $2,760 was recorded during the three months ended September 30, 2025 and 2024 for minimum state required tax payments only and there were no federal income tax provisions recorded due to net operating loss carryforwards (“NOLs”) available to offset taxable income. Application of available NOLs to potential future taxable income would minimize any tax payment requirements. NOLs arising in tax years beginning after December 31, 2017 are limited to 80 percent of taxable income per the Tax Cuts and Jobs Act (“TCJA”). As such, the future utilization of all federal NOLs available to the Company is limited to 80 percent of the resulting taxable income. The Company's tax loss carryforward as of September 30, 2025 was approximately $34,500,000. Given the cumulative taxable losses for the last three years, excluding one-time items, the expectation for utilization of the estimated tax loss carryforward is not likely, and as such, the future realization of this continues to be uncertain. The valuation allowance was adjusted to continue to fully offset the net deferred tax asset as there is sufficient negative evidence to support a full valuation allowance.
DEFERRED COMPENSATION	E) DEFERRED COMPENSATION The Company’s deferred compensation liability is for a current officer and is calculated based on years of service and compensation, along with various assumptions related to expected retirement date, discount rates, and mortality tables. The related expense is calculated using the net present value of the expected payments and is included in selling, general and administrative expenses in the condensed consolidated statements of operations. The deferred compensation liability recorded at September 30, 2025 and June 30, 2025 is $2,387,338 and $2,226,454, respectively. Compensation expense of $160,884 was recorded during the three months ended September 30, 2025 as a result of the increase in the deferred compensation liability for the current officer, due mainly to the annual increase in the future payments earned under the arrangement due to completing an additional year of service, as well as a slight decrease in the discount factor. The discount factor used to calculate the net present value of the liability was 5.81% at June 30, 2025 and declined to 5.53% at September 30, 2025. For the three months ended September 30, 2024, compensation expense of $197,374 was recorded under this arrangement.
RECENT ACCOUNTING PRONOUNCEMENTS	F) RECENT ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements In December 2023, FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU focuses on income tax disclosures around effective tax rates and cash income taxes paid and requires consistent categories and greater disaggregation of information in the rate reconciliation, income taxes paid disaggregated by jurisdiction and certain other amendments. The new guidance was adopted prospectively as of July 1, 2025 and ASU 2023-09 does not mandate retrospective disclosure. Given the ASU relates solely to disclosure requirements, adoption does not have a material impact on the Company’s financial position, results of operations or cash flows. See Note 4 for further information. Recently Issued Accounting Pronouncements Not Yet Adopted In March 2024, FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220 40): Disaggregation of Certain Income Statement Expenses, which was subsequently amended by ASU 2025-01 in January 2025 to clarify and refine certain requirements. The ASU requires public business entities to disclose in the notes to the financial statements the amounts of employee compensation, depreciation, amortization, and inventory costs included in each relevant income statement line item. The guidance also requires disclosure of other expense categories if they are significant to an understanding of the entity’s financial performance. The amendments are effective for annual periods beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027 and entities are required to apply the amendments retrospectively. Early adoption is permitted. The Company will evaluate the impact of the standards on its Consolidated Financial Statements and related disclosures. While the adoption of ASU 2024-03 and ASU 2025-01 will not affect the Company’s recognition, measurement or presentation of expenses on the face of the Consolidated Statements of Operations, it is expected to result in expanded disclosures in the notes to the Consolidated Financial Statements. The Company has not yet determined whether it will early adopt the guidance.
