Unisub Hardboard Puzzles are perfect gifts for the young and the young-at-heart. Imprinted with a class picture, a team photo, a cartoon character or a gag saying, these jigsaw puzzles are not only versatile, but so affordable you'll want to stock them as an imprintable gift item for every occasion throughout the year. Unisub's high density hardboard jigsaw puzzles have great looking black edges that nicely complement all artwork. They sublimate better and last longer than the usual cardboard puzzles. Each puzzle includes a clear plastic presentation case to use for attractive display. The finished puzzles can be placed in the stiff clear plastic envelopes that are packed in every case.
