This is an awesome hammer style bubbler crafted by GRAV Labs. It is all clear for a nice clean look and is adorned with the GRAV Labs logo on the water chamber of the bubbler. The height for this bubblers is about 4 inches tall.
It came with stress cracks I couldn't see till after I used it. I emailed and got no response. I understand glass can have issues but I don't like no response to an email
