Black Leaf Carb Cap Spinner Clear Glass

This is the clear version of Black Leaf's spinner carb cap, made from colourless borosilicate: a raised tower with an open chimney above six diagonal air channels. As you draw, those channels create a vortex inside the banger that sets terp pearls spinning and spreads the concentrate evenly across the hot surface. Black Leaf also sells a speckled, mushroom-shaped version — a separate article with a different diameter.
