Did you drop your favored Horizon Falcon tank? I hope not, but it does happen. Bubble glass holds more juice, but is more susceptible to cracking, since it sticks out further than the atomizer.

Or you would rather insure your tank by having a spare glass, just in case?

Never fear! We've got your back. You have options - a 5mL regular flat glass, the 7mL bubble, or the 7mL bubble in rainbow! Your choice. 

Sold individually per order.
