Description

The Grotto is MJ Arsenal’s hollow-bottom hand pipe, named for shoreline caves and shaped around the same idea: a scooped underside that fills the palm. Thick borosilicate, an 18mm bowl and a left carb, in a 4.5″ body that cleans in one soak.

Why it stands out

• Hollow-bottom base for a rounded, secure grip

• Straightforward interior — no trap for residue
