To Boldly Go-17oz straw tumbler

Boldly go! But stay hydrated with a beautiful cup! I am absolutely IN LOVE with the colorful swirls on the back of this one! The technique used to make this style is super unpredictable, so no two galaxies are the same! There are also some swirls that glow in the dark, but it requires a UV/sunlight charge. The last photo shows the glow after just a few seconds in the sun!
This tumbler comes with a stainless steel straw and screw on lid.

This tumbler is handcrafted with epoxy resin, so it does require some special care:
- it is NOT dishwasher or microwave safe
- do not drop it, or it may crack or shatter. I leave the bottom stainless steel exposed to help reduce this possibility, but it is still a very real possibility.
- do not leave it in a car or any other hot environment
- do not scrub with a rough sponge or anything else that may scratch it
