ABSTRACT:
The business form set includes a plurality of rectilinear sheets forming a multi-ply set including first, second, third and fourth sheets. The first first, second and third sheets are joined one to the other at least along a margin and the fourth sheet is formed of plastic material sealed along three of its four margins to corresponding margins on the backside of the third sheet to form an envelope. The fourth margin of the fourth sheet is inset from the corresponding margin of the third sheet whereby the third sheet margin forms a flap. The first and second sheets are carbonless whereby information printed on the first sheet appears on the second and third sheets. A sample vial may be disposed in the envelope and sealed whereby the vial and information on the third sheet remain one with the other.
