This is it. The others are just pretending, just trying to be as cool and as popular. The Upright Upline bubbler is a powerhouse of smoking madness. A huge chamber is encompassed by concentric rings that help to percolate and protect the large body of this big bubbler.
The mouthpiece features the same Upline rings that reinforce the glass and look boss. This piece takes 14mm male accessories and works well as a pipe or rig.
The functionality is a lot like the Slush cup design with even more functional filtration.
