Now digital decorators can have the vibrancy of sublimation transfer on a durable, lightweight mug. PolySub Mugs are made of a specially formulated polymer that makes them safe for use at the beach, swimming pool, and any other place where breaking a ceramic or glass mug would cause a safety hazard. PolySub Mug's bright white finish produces a brilliant color transfer that's both beautiful and dishwasher safe. The advantages over ceramic mugs include lower shipping costs, easier handling, and elimination of loss due to breakage. Great for family photos, pet photos, baby photos, sports logos, or monograms. These mugs are a perfect personalized gift for any holiday or special occasion. To assure consistent quality transfers, Condé offers an aluminum insert tool that fits inside the mug during sublimation.
