20oz White Tumblers | Sublimation Blanks
Sublimation ready 20oz tumblers with slide lid
** TAPERED **
** The time/temp I use for these 20 oz tumblers in my convection oven is approximately 360 degrees for 4 minutes. If you're doing a double sided design, I recommend rotating halfway through. Definitely make sure you have an extra tumbler to test in your own oven or press to find your own "sweet spot" and make sure you have an oven thermometer to verify the true temperature of your oven. Shrink Wrap is required for sublimation tumblers created in convection ovens. **
Tumblers are double-walled, vacuum insulated tumblers and will keep any beverage hot or cold. Vacuum seal keeps liquids and carbonation fresh. 100% BPA and Phthalate Free.
** Tumblers are not microwave safe. Some dishwashers use high heat/dry cycles, possibly causing the ink to reactivate and cause running, I recommend hand wash only. **
