Pennywise...clowns are creepy and this one tops the list. What could make this tumbler even more scarier you ask? Turn out the lights and let this glow in the dark tumbler turn up the fright. This Makerflo 20 oz tumbler is made of a stainless steel double-wall and is vacuum insulated, with a clear sliding classic lid and a clear straw, and is BPA free. It is capable of retaining cold temperatures for 24+ hours or warm temperatures for up to 8 hours. We put this one on our green glow in the dark tumbler.
