This is a tank protector I designed to fit Kanger SUBOX and TOPBOX atomizers.
The tank cover does an outstanding job of protecting the alarmingly fragile glass tank; a friend of mine broke 2 tanks ($26 each!) before putting one of my tank protectors on. He's dropped it a few more times, and the tank lived where the others have shattered. It works!
It has a window on both sides so that you can view the juice remaining, and fits over the standard delrin tip. Never break a tank again!
