No 40oz for me. I can't buy them in my county. And I'm not going to Madison county or Tennessee to get a 40 LOL. Wonder if they make one to fit a Mich ultra can. LOL
They make them to fit Skinny tall cans, BL Aluminum Cans, Red Bull Cans, Monster Energy Drink Cans, 24oz Tall Boys, Water bottle, and universal water bottle koozies.
CHECK OP FOR UPDATE!!
Ordered first batch!
