Raising Wild Things 20oz Skinny Tumbler
This tumbler is stainless steel, double walled and vacuum sealed!
It comes with a slide to close lid and plastic straw.
All of my tumblers are sealed with epoxy, to ensure that the inside design and glitter are protected. This gives it a glass like smooth finish!
My epoxy is one of the highest rated for UV protection. (All epoxy will yellow over time with long term sun exposure, however the epoxy I use has added ingredients to prolong this)
