These simple beaker bong designs from Black Leaf have neon colored silicone sleeves around the neck and around the base to add some uniqueness and to help give a little better grip on the most important areas of the bong. There is one wrap of silicone around the base which adds stability and stops it sliding around on smooth surfaces, then there is another around the neck of the bong to give you some more grip when you want to pick it up. The silicone wraps themselves have been 'swiss-cheesed' so that you can still see through them and check out how milked up it is before you open the side mounted carb hole and clear it like a boss. The removable downstem has a 14.4mm female ground glass joint and they include a 14.4mm male bowl with roll stops to finish it off.
