Hillside Glass 14mm Double Wall Quartz Cup

Double-wall construction sandwiches an insulating air gap between the inner and outer quartz layers, dramatically improving heat retention compared to single-wall bangers of the same size. The trapped air acts as a thermal buffer that slows heat loss, keeping the bucket at dabbing temperature longer and allowing users to take multiple draws from a single heat cycle without reheating. The 14mm male joint fits standard rigs, and the flat-top design accepts carb caps of all styles. The opaque outer wall adds a frosted visual aesthetic that distinguishes the cup from clear quartz alternatives. For low-temperature dab enthusiasts who chase long, terpene-rich sessions without constantly reaching for the torch, the double-wall cup is one of the most effective thermal upgrades available. Crafted from 100% quartz for flavor purity.
