Silicone Bongs are great for traveling, clumsy people, or those just looking for an effective bong that won't break the bank. These bongs are made from food grade, BPA-free silicone that are 100% safe to toke from. Silicone bongs are mostly unbreakable, easy to pack, and can be made into fun shapes and sizes. Because these water pipes are made from silicone, they will feature a stainless steel or glass bowl piece.
