Add some color to your piece with a fat bubble bowl from Grav Labs. These bowls have a big bowl depression. The Bubble shape keeps the outer glass cooler to the touch and the beads help you grip it easily when sliding it out after a nice, hefty hit.
The Grav Labs bubble bowl has a 14mm male joint and is 2 inches high.
Not Sure What Bowl Size You Need?
To determine the bowl size you need simply measure the slide joint opening with a metric ruler. The slide joint opening is the hole near the base of the water pipe where the downstem reaches into the water. The measurement will be either 14mm or 19mm (or, for small water pipes, 10mm).
