This is the replacement glass bubbler for the XVape Vista Mini 2. Having spare parts is ideal in case you lose or break the original. The bubbler is made from handblown, borosilicate glass and has a red line on the side to show you the optimal level for water. This piece does not include the mouthpiece or carb cap, it is solely the bubbler. This glass bubbler is not meant for other vaporizers, it is meant for the Vista Mini 2 exclusively.
