You have seen brass knuckle dusters before but have you seen a glass knuckle bubbler? Get ready to get knocked out!
This custom bubbler holds water and percolates smoke as you puff on a blunt or a doobie in style. Now available in a variety of colors! Make sure to grab some blunt wraps or cones to go with this bad boy.
