Details of 20oz skinny straight sublimation tumbler:
304 kitchen-grade stainless steel
Individually boxed and bubble wrapped
** Please note that these wraps provide extra insulation, so you might need to adjust temperature and time. We recommend practicing on your "messed-up" tumblers first, as it could take a few trials for you to get used to the wrap! However, you'll love not having to purchase disposable wraps over and over again.
