One question we consistently get asked is do your Vape Bands / Vape Rings fit around a Sub-Tank?
The answer is yes.
The vape bands are made out of silicone so tend to be very stretchy and can fit around most standard vape pens.
The most common vape pens that I have seen them used for is the KangerTech Sub-Tank / Sub-Box Mini.
They fit around these extremely easy, barely stretching at all in the process.
You don't have to worry about ruining your vape bands when they stretch, as due to the material, they tend to bounce back to shape really well.
