Review on 🔒 Pack of 15 Leak-Proof Lids: North Mountain Supply 38mm Black Plastic Phenolic Polyseal Screw Caps with PolyCone Liner by Ben Diesel

These baseball caps are nice but only fit the round Boston Growler I have. I also have several 32oz and 64oz growlers with side loop handles and they don't fit any of them. Reviews of other caps say 38mm is the same as 1 1/2 caps but I can actually fit this cap in one of them. I will be keeping these for use with the Boston Round Growlers but I really don't know what to order now as most other lids also state they are 38mm.
