Pocket bubblers are versatile portable and fun! They can fit a 10mm flower bowl a 10mm quartz banger for concentrate or even a well-rolled joint or blunt. The bubbler chamber adds a little water filtration while still keeping the piece nice and compact. The spherical bubbler stands sturdily on its flat bottom and fits very discreetly in your hand. This piece comes with a 10mm Cup Bowl but can be used with a 10mm banger or a pre-rolled joint or blunt.
