This glow in the dark glass bong is clear and many colors can be seen under the light. There is cactus-shaped glowing material inside the body. The glowing material makes the bong glows bright green in the dark! A pretty heady feature! The bong is approximately 12.3" in height and 448.4g in weight which is a bit heavy when you hold it in your hand. It features high-quality glass so you won't worry about breaking it down on the floor. The set comes with a 14mm joint size female removable downstem and the male bowl piece.
