This listing is for black base with glitter and mica swirled on a stainless steel insulated tumbler. Shown on a can/bottle cooler, but can be made on any style of cup as well.  Choose 3 colors of glitter and 3 colors of mica powder. I have all colors. If you want it just like the picture, write that in the comments. Turn around time is 2 weeks.
