Our snowglobe tumblers are acrylic and hold 16oz of liquid. They are made in house with this one featuring a mixture of pink and white glitter so, when shaken, the glitter moves and falls like that in a snowglobe. To activate- shake the tumbler To store- store this tumbler upside down and avoid standing for long periods of time To clean- handwash only, avoid soaking or rubbing and boiling hot water Would like a custom tumbler made just for you? pop me a message
