Made of strong borosilicate glass and food-grade silicone, the Blaster is ready to demolish whatever you toss its way. Extremely sturdy with two base options to choose from (glass or silicone), it has 4 distinct functions expertly packed into a relatively compact, futuristic device. Use the glass base for the visual of the smoke gathering inside, or swap it out for the silicone base to create a totally unbreakable device that you can take on the go.
