Description

The Grotto is MJ Arsenal’s ergonomic hand pipe, named after hidden shoreline caves and shaped to match — a hollow-bottom base that gives the pipe a rounded, palm-filling feel instead of the usual flat spoon profile. It is pulled from thick borosilicate with a generous 18mm bowl and a left-side carb, and it wipes out easily because there are no tight internal corners.

Why it stands out

• Hollow-bottom base gives a rounded, comfortable grip
• Large 18mm bowl diameter for a full pack
• Thick borosilicate that survives pocket and bag travel
• Offered across nine colorways
