Product Specifications

Why Choose Human Grade Glass Adapters

Instead of tracking down and buying single adapters one at a time whenever a new piece doesn't quite match your setup, this 5-piece set covers the most common 10mm, 14mm, and 18mm joint mismatches in one purchase. The reclosable storage container also keeps the whole set together in one place, so you're not left searching for a loose adapter when you need it, and the handmade borosilicate construction holds up to regular use.

Ideal For

This set is ideal for anyone who owns multiple pieces with different joint sizes, or who frequently swaps rigs, bongs, and bubblers between sessions. It's also a practical pickup for anyone who's ever had to pass on a piece they liked simply because the joint didn't match what they already own.

Care & Maintenance

Rinse after use and clean periodically with isopropyl alcohol to prevent residue buildup at the joints.
