Quartz Cup Concentrate Nail
Quartz is harder than borosilicate glass with a higher melting and working temperature, making this handmade concentrate nail from American Glass Works an ideal spare or replacement nail for any vapor globe set and a step up from boro glass! This Quartz cup concentrate nail is meant for smoking BHO (butane honey oil), wax or other concentrates from any bong or oil rig along with a vapor dome and adapter (not included). Bead stoppers allow it to sit safely on a 14.5mm or 18.8mm glass-on-glass joint. Choose joint size when ordering.
