12 Pack 38mm Growler Caps Growler Lids Poly Seal Screw Caps Poly Seal Growler Caps Compatible with 1/2 Gallon and 1 Gallon Glass Gallon Jugs Replacement for Homebrew Wine Making Beer Brewing, Black

I like these a lot! I make kombucha, and the metal lids I have were rusting. These are easy to clean- the seal pops off so you can clean inside it. I haven't experienced twisting them so tight they break, they seem durable to me. They fit my growlers perfectly, and my kombucha turns out carbonated which tells me the seal is working well. I didn't notice a stinky smell like others mentioned, but of course I washed before using them.

I have 1/2 gal glass jugs, and these were a perfect fit, for my sauce, tight seal.

I have repurposed 1 gallon wine jugs to be used as water jugs. The cheapy metal/aluminum? lids that come with the wine are poor quality and I don't trust them. If you store your bottles in an upright position (as you should) they work great for protecting your beverages from the elements, etc.

Caps serve their purpose but could be a little thicker for clumsy people like me who drop things a lot. Overall good product for its intended purpose. It fits and seals with no complications.

I have these jugs that originally had metal caps that eventually rust is become misshapen. These caps are perfect substitute and they are very secure screw tops. So glad I found these.
