Vaso Mason de Vidrio Acanalado

I've been taking iced tea to work in this every morning and it hasn't leaked in my bag once. The glass is thick enough that it feels sturdy without being heavy, and it slides right into my car's cup holder.

Didn't expect to love a glass this much but the ribbed texture actually helps me grip it when my hands are wet from washing dishes. It slides into my car's cup holder without wobbling, which was the whole reason I bought it. My tea stays put on the commute and cleanup is a quick rinse.

The ribbed texture makes it so much easier to grip than my old smooth tumbler, especially when my hands are wet from washing dishes. It fits perfectly in my car's cup holder too, which was the main reason I bought it. Been using it daily for iced tea and it hasn't leaked once.
