BLANK 20 oz Glitter Skinny Tumbler includes a straw and ships in individual white boxes.  These are for SUBLIMATION purposes. We have the same tumblers Non sublimation located here:  Vacuum seal keeps liquid fresh and drinks cold! Leak Proof Lids!  Some dishwashers use high heat to wash which may possibly causing the ink to reactivate. I recommend to my customers to hand wash!  I press these by placing the image down and then turn tumbler and press the other side as well!  Mock Ups & Transfers coming soon!
