There is an interesting design on the BUSHIDO MOD - you just need to turn the mod over and unscrew the cap to refill the squonk bottle, instead of pulling the whole bottle out of your mod. This could bring you a much more convenient experience on using squonk mods and could always keep your mod clean on the inside.
The main frame and the doors fo the BUSHIDO MOD are made from CNC-milled all aluminum alloys.
