Abstract
A sample of a cosmetic, such as a color, or a fragrance, is enclosed in a retaining cavity contained in a sampler. The sampler includes a base ply with a closure ply affixed to one side to cover a hole punched through the base ply to define the retaining cavity. A film ply is adhesively affixed to the other side of the base ply, also covering the punched hole, to thereby enclose the cosmetic in the retaining cavity. To use the sampler, the film ply is removed exposing the cosmetic. In a preferred embodiment, the sampler is made by punching a hole through a laminate formed of a base ply lying between a base ply adhesive and backing ply on one side and a liner adhesive and a liner ply on the other. The liner ply is removed and a closure ply affixed to the liner ply adhesive to form a retaining cavity. A cosmetic is then placed in the cavity. The backing ply is then removed, along with any residual cosmetic, and replaced by affixing a film ply to the base ply adhesive.
