10mm Male Hollow Bubble Glass Bowl

A hollow stem and rounded bubble chamber define this 10mm male glass bowl, designed for smaller rigs and dab setups where airflow efficiency matters as much as fit. The hollow construction reduces overall weight while allowing unrestricted airflow from bowl to downstem, minimizing drag during inhalation. The bubble shape at the top provides a generous packing area for dry herbs, and the rounded walls naturally funnel ash toward the center rather than letting it clog the sides. Made from borosilicate glass, it withstands repeated heating and cooling cycles without cracking or discoloring. The 10mm male joint fits snugly into 10mm female water pipes and rigs. For shops, replacement bowls are among the highest-turnover accessories on the shelf, and offering the less-common 10mm size ensures you capture sales that competitors stocking only 14mm miss.
