Novelty UV gas mask bong! One size fits all due to its adjustable straps.
How to use:
Fill your bong with herb and water. Pull the mask over your head and secure the straps in such a way that the mask is tight on your face and doesn't let any outside air in. Attach the bong to the mask and spark away!
You can open the side valve to inhale fresh air through the mouthpiece inside the mask.
