Unlike common paper cards, the edges and corners won't tear or fray. If necessary, they can even be cleaned with a damp cloth! Use them to create stunning and long-lasting business cards, frequent buyer cards, membership cards, affinity cards, coupons, invitations, playing cards, game cards, bookmarks, etc. Sublimatable Business Cards measure 2-1/8" x 3-3/8" x .008 thick.
