We're awesome, but we're not perfect. This jar is proof of that. It used to be our XL UV Screw-Top, but fans weren't happy with the seal. And you know what? Neither were we. So we went back to the lab and came up with double-wall protection to ensure maximum freshness. We learn from our mistakes. Just like Einstein.
