We just love getting new glass in. Especially when the style is fresh, and the price is right! What's fresh about these is the gridded inline. Everyone wants to get on the gridded tip and these Slim's inline bubs from Green Goddess Glass are a sure shot. We threw some water in them and got maximum diffusion results! They come clear or with a worked section on the splash guard and a matching slide. Slim also makes another stand up inline bubbler. These come gridded and are available in clear or worked as well. Kulture always needs those slide holders too so we picked up a few. Check 'em out! They are compact and hold 5 slides each. All of our slide holders are available for purchase.
