These are extra caps that came from some kind of mix up I think. I don't have bottles to go with them. Selling the lot of 600 caps for $40.00 or let me know if you have something cool or useful to trade. Located in Raymond, NH. These caps are 18.. x 400 thread. tamper Evident. Gold in Color. Fit the 50ml Maple Leaf shaped glass bottles that CDL sells and fit many other small glass bottles as well.
