100 Pcs Caps for Empty Juice Bottles, Tamper Seal Lids 38 mm Plastic Bottle Caps Container Lids Bottle Caps for Crafts DIY, 4, 8,12, 16, and 32 oz Container(Black)

I ordered these for a juice order I had. The tops came quickly which was a plus. The quality and durability of them are good , I didnt experience any leaks from the seal and they all fit perfectly. I had a few that didn't fit but overall great product.

I've purchased 'standard' tamper proof caps for my 16 oz drink bottles in the past with no problem. However, these simple did not fit. They were just large enough not to screw down at all. You could push them down due to the tamper proof ring but of course it wasn't sealed. What's even worse then that is they were just packaged loosely in a box without a plastic bag or any attempt at keeping them sanitary. Needless to say I sent them back for a refund.

Did not fit the bottles. Smh

If you, like me, are wondering if these will fit your bottles, just measure! These lids are 38 mm, or about one and a half inches. The other sizes are quite different, so if you are getting close to one and a half inches, these will fit. The extra 'snap' when closing is the 'tamper proof' seal moving over the ring that is part of your bottle. I think it gives that extra seal to hold in carbonization during my second ferment of kombucha and water kefir. Good product, and a decent price.
