Both. Despite the name, MJ Arsenal blunt bubblers in this collection are designed to accept any rolled product that fits the joint diameter — blunts, pre-rolled joints, cones, and hand-rolled joints all seat in the same opening without any adapter needed. The Martian Original is sized for a standard-thickness blunt or pre-roll, which covers most factory pre-rolls sold at LA dispensaries. The Martian King Toke accommodates wider rolls, including king-size cones and fatter blunts wrapped in larger wraps. For thin pre-rolls or skinny joints, a standard-fit blunt bubbler may sit loose — wrapping a thin paper twist around the base of the joint takes up the gap and seats it cleanly without affecting the draw. For pre-roll smokers in particular, a blunt bubbler is the underrated upgrade: the same pre-roll smoked through water hits noticeably smoother and cooler than dry. The /collections/blunt-bubblers selection at Angies Boutique covers single, double, and king-size variants stocked at the shop at 838 N Broadway.
