Ezo-lovers, welcome! I think you're going to love this stuff.
I use one of these all the time. I just cut the big ol' wax roll into the length I like, throw a stack of these wax squares in my little box, and drop the box in the case. It's fantastic. And it's a great, inexpensive way to keep your in-use cushions ready-to-use!
Grab this Travel Case for half-price when you purchase it pre-loaded with Teeth Cushions!
