Re:	STEN Corporation
	Post-Effective Amendment No. 1 to Form S-1
	Filed December 31, 2007
	File No. 333-140852

Dear Mr. Brimmer:

	This is to advise you that we have reviewed only those
portions
of the above registration statement that relate to the legal
opinion
and have the following comment.

Form S-1
Legal Opinion
1. Revise to file a legal opinion that opines that the notes will
be
or are "binding obligations" of the registrant.

No further review of the registration statement has been or will
be
made.  All persons who are by statute responsible for the adequacy
and accuracy of the registration statement are urged to be certain
that all information required under the Securities Act of 1933 has
been included.

	You are also reminded to consider applicable requirements
regarding distribution of the preliminary prospectus.

	We urge all persons who are responsible for the accuracy and
adequacy of the disclosure in the filings reviewed by the staff to
be
certain that they have provided all information investors require
for
an informed decision.  Since the company and its management are in
possession of all facts relating to a company`s disclosure, they
are
responsible for the accuracy and adequacy of the disclosures they
have made.

	Notwithstanding our comments, in the event the company
requests
acceleration of the effective date of the pending registration
statement, it should furnish a letter, at the time of such
request,
acknowledging that

* should the Commission or the staff, acting pursuant to delegated
authority, declare the filing effective, it does not foreclose the
Commission from taking any action with respect to the filing;

* the action of the Commission or the staff, acting pursuant to
delegated authority, in declaring the filing effective, does not
relieve the company from its full responsibility for the adequacy
and
accuracy of the disclosure in the filing; and

* the company may not assert this action as defense in any
proceeding
initiated by the Commission or any person under the federal
securities laws of the United States.

	In addition, please be advised that the Division of
Enforcement
has access to all information you provide to the staff of the
Division of Corporation Finance in connection with our review of
your
filing or in response to our comments on your filing.

      We will consider a written request for acceleration of the
effective date of the registration statement as a confirmation of
the
fact that those requesting acceleration are aware of their
respective
responsibilities under the Securities Act of 1933 and the
Securities
Exchange Act of 1934 as they relate to the proposed public
offering
of the securities specified in the above registration statement.
We
will act on the request and, pursuant to delegated authority,
grant
acceleration of the effective date.

	If you have any questions, please feel free to call Michael
R.
Clampitt at (202) 551-3434. In his absence, you may contact Mark
Webb
at (202) 551-3698.


      Sincerely,


							Mark Webb
