Glass Tip 7-hole Spiral, 10 mm - Greendream

Glass tips with spiral airflow for perfect cooling effect and flavor development.

10mm diameter. 7 holes!

These special glass filters are carefully handcrafted.

Several, or rather seven, small glass tubes are fused together in an outer tube while continuously rotating and heating them in a flame. The rotating motion and targeted heat exposure create the characteristic spiral shape of the inner channels. Due to this artisanal process, the size and shape of the holes may vary slightly, making each filter unique. Made from heat-resistant borosilicate glass.
