Replacement glass for the Smok TFV4 Sub Ohm Tank.
Accidents happen, but if you do manage to break the glass in your TFV4, there's no need to throw away the entire tank.
Now you can grab a replacement glass to fit your device and you can be up and running again. This will definitely do the job if you ever experience any cracks or leaks from your tank.
This Pyrex gass tube is a spare part only!
