Replacement gaskets for the flip-tops on our EZ cap bottles.
I don't know how you could screw these up, but I suppose certain manufacturers could find a way. Found them to have multi uses as well!
Using these for the first time. Most of them fit well, but a few have been too thick to fit onto the bottle top. There is a little variability in their thickness.
Grolsch gaskets can hold your guitar strap on the strap buttons too.
These gaskets are ver thick and stiff and are a pain to put on, at least the first time. I’ve just used them for the first time, so I’m waiting to see how they perform. Better be good for all the trouble.
