You have seen brass knuckles before but have you seen a glass knuckle bubbler?
This custom bubbler holds water and percolates smoke as you puff on a blunt or a doobie in style.
Measures 5.5 inches tall and features durable, clear borosilicate glass. Spill-resistant design. Works with blunts and cones. One size fits most hands.
