The MJ Arsenal Blunt Bubbler Bumpers are designed to fit snuggly on the base of your Martian Blunt Bubbler from MJ Arsenal. The bumper protects your surfaces when passing the bubbler, and it adds a bit of comfort to the grip. They are made from soft and versatile silicone, which makes them easy to wash with warm water and soap. Each pack comes with three bumpers in black, green, and blue. Don’t leave your Blunt Bubbler open to potential harm.
