Midnight Glass Ash catcher in a unique RBR (Refined Bell Recycler) Shape. This RBR Ash Catcher comes in both 14mm or 18mm options to fit bongs of all sizes. Fitted with a matrix perc, this ash catcher equally diffuses the smoke in 36degrees around the perc, and sends water spiraling into the second chamber. This is our version 1 model of the RBR style ash catcher and hope you all enjoy it. We find this ash catcher hits and functions best when a constant, smooth pull is drawn, as compared to a fast and aggressive pull. 3.25" Tall, 5" Long/wide 14mm or 18mm Joint options Matrix perc w/ Recycler function Midnight Glass Logo
