GRAV® Coffee Mug Pocket Bubbler - Assorted Colors

A pocket bubbler shaped like a coffee mug, handle included — GRAV being GRAV.

The joke works because the function is real. The mug form gives a wide, stable base and a genuine handle to hold, which is more ergonomic than most pocket bubblers that ask you to grip a slick glass body. Pocket-sized means the water volume is small, so it needs topping up more often than a full piece — that's the trade for portability.

Thick borosilicate. Assorted colours, so the finish varies.

Suits: travel, gifting, and anyone who appreciates glass with a sense of humour that still performs.

For adults 21+. Sold for use with legal materials only.
