Pulsar Glass Knuckles Bubbler | 5.5 Inch
Pulsar Glass Knuckles Bubbler | 5.5 Inch
This unique bubbler is made from durable borosilicate glass and it is shaped like a pair of brass knuckles. It measures 14 cm / 5.5 inches. Because of the knuckle shape, it is a nice bubbler to hold in your hand. You can use it at home or take it on the go with you. This bubbler can be used with blunts and cones.
Using it is simple; just add a bit of water in the bubbler, load the bowl with your blunt or cone and fire it up for a quick, hassle-free hit! You can also use herbs with this device, however we do suggest using a screen to prevent herbs and ash from traveling into the bubbler and befouling the water.
This bubbler is a must-have if you want to smoke a blunt or cone but also have the filtration of a bubbler. Order your Pulsar Glass Knuckles Bubbler right here at GrasscityShop US.com for an unbeatable price.
