Easier than corks!! Look nice on bottles too.

They work really well

I feel confident with the seal on these screw-top lids. They do not work on ALL bottles with threaded mouths, so try before you rely on them if you recycle your own. The threaded bottles sold by this company work best. Super easy for beginners and very cost effective.

The seal is not as tight as I would like them to be.

I use 64 ounce growlers to bottle beer and these caps work great. Even after opening, they will keep the growler carbonated for a couple days, although I rarely have one last that long...
