20 oz white sublimation skinny tumbler. These have a straight body, they are not tapered. BPA free lid with rubber seal ring. Double wall vacuum insulated. Tumblers each come in a box with a lid, metal straw and plastic straw.
We have had success sublimating these tumblers using a convection oven set at 375 degrees Fahrenheit for 6 minutes, turning at 3 minutes.
