I love these tumblers! They are double wall, seamless stainless steel that keep drinks hot or cold for hours and don't condensate. I have left mine on the counter overnight with ice in it and the ice is still there in the morning.
Super easy to clean and a lot safer than plastic. Simply hand wash and reuse.
The design is sublimated into the tumbler and won't come off. Techincally they are dishwasher safe but I don't recommend it as it will cause the image to fade.
It measures 8 1/4" tall x 3" wide.
