Carbo-Caps: Revolutionary Carbonation Solution

The caps truly do work ✨

Despite trying lots of small tweaks and changes, my kombucha was flat. After finally guessing it was a poor seal on my swing top bottles, I switched to some GT Synergy bottles with these caps. I went from nearly flat kombucha to huge amounts of carbonation, filling up over half the glass! Great little inventions.

Effective, but fit issues

The caps seem to be good quality, but the fit is compromised by an O-ring that is too thick and doesn't let enough threads engage.
