      RE:   MAN SANG HOLDINGS, INC. REGISTRATION STATEMENT ON FORM S-8 FOR
            1,900,000 SHARES OF COMMON STOCK

Ladies and Gentlemen:

      We have acted as special Nevada counsel to Man Sang Holdings, Inc. (the
"Company") in connection with its filing with the Securities and Exchange
Commission on or about the date hereof of a Registration Statement on Form S-8
(the "Registration Statement") for the registration under the Securities Act of
1933, as amended, of 1,900,000 shares of Common Stock, par value $0.001 per
share, of the Company (the "Shares") to be issued under the Man Sang Holdings,
Inc. 1996 Stock Option Plan (the "Option Plan"). Capitalized terms used herein
and not otherwise defined shall have the meaning set forth in the Registration
Statement.

      We have been informed that item 601 of Regulation S-K and the Instructions
to Form S-8 require that an opinion of counsel concerning the legality of the
securities to be registered be filed as an exhibit to the Form S-8 Registration
Statement if the securities are original issue shares. This opinion is provided
in satisfaction of that requirement as it relates to the Registration Statement.

      We have examined: (i) Articles of Incorporation of S.B.H. Ventures, as
filed with the Secretary of State of the State of Nevada on November 14, 1986;
(ii) Articles of Merger merging Unix Source America and S.B.H. Ventures and
changing the name of S.B.H. Ventures to Unix Source America, as filed with the
Secretary of State of the State of Nevada on December 31, 1991; (iii) the
Company's Restated Articles of Incorporation, as filed with the Secretary of
State of the State of Nevada on January 12, 1996; (iv) the Company's Certificate
of Amendment of Articles of Incorporation, as filed with the Secretary of State
of Nevada on June 7, 1996; (v) the Company's Certificate of Designation,
Preferences and Rights of a Series of 100,000 Shares of Preferred Stock, $.001
Par Value, Designated "Series A Preferred Stock", as filed with the Secretary of
State of the State of Nevada on June 27, 1996; (vi) the Company's Certificate of
Designation, Preferences and Rights of a Series of 100,000 Shares of Preferred
Stock, $.001 Par Value,

Designated "Series B Preferred Stock", as filed with the Secretary of State of
the State of Nevada on June 27, 1996; (vii) the Company's Certificate of
Decrease in Authorized Shares Pursuant to NRS 78.207, filed with the Secretary
of State of the State of Nevada on October 8, 1996; (viii) a Certificate of
Existence, issued by the Secretary of State of the State of Nevada on June 4,
2002, certifying among other things that Items (i) through (vii) above
constitute all organizational documents on file for the Company in the office of
the Secretary of State of the State of Nevada; (ix) the Company's Amended
Bylaws, as certified by the Company's Secretary as of February 25, 2005; (x) the
Plan, and such other records and documents as we have deemed advisable in order
to render this opinion. We have relied upon the certificates of all public
officials and corporate officers of the Company with respect to the accuracy of
all matters contained therein, including as to the number of shares of the
Company's common stock which are issued and outstanding. We have assumed the
authenticity of all documents submitted to us as originals, the genuineness of
all signatures, the legal capacity of natural persons and the conformity to
originals of all copies of all documents submitted to us.

      Based on such review and assumptions, we are of the opinion that when
issued pursuant to the Plan, the Shares will be legally issued, fully paid, and
non-assessable. We express no opinion regarding compliance with any blue sky or
similar laws relating to the sale or distribution of the Shares.

      Nothing herein shall be deemed an opinion as to the laws of any
jurisdiction other than the State of Nevada.

      This opinion is rendered solely in connection with registration and
issuance of the Shares. It may not be relied upon for any other purpose, or
reproduced or filed publicly by any person, without the written consent of this
firm. Notwithstanding the foregoing, we consent to the filing of this opinion as
Exhibit 5.1 to the Registration Statement. In giving this consent, we do not
thereby admit that we are within the category of persons whose consent is
required under Section 7 of the Act, the rules and regulations of the Securities
and Exchange Commission promulgated thereunder, or Item 509 of Regulation S-K.

      This opinion letter is rendered as of the date first written above and we
disclaim any obligation to advise you of facts, circumstances, events or
developments which hereafter may be brought to our attention and which may
alter, affect or modify the opinion expressed herein. Our opinion is expressly
limited to the matters set forth above and we render no opinion, whether by
implication or otherwise, as to any other matters relating to the Company or the
Shares.

                                       Very truly yours,

                                       /s/ Lionel Sawyer & Collins
