The Wulf Duo magnetic rings are used to easily snap your cartridges into your Wulf Duo or other Magnetic cartridge vapes to make it easy to take in and out of your Duo. You just screw your cartridge into the magnetic rings and you can slide it into your vape and right back out.

Comes in a large variant for your 0.5ml cartridges to reach the top of your duo and a small variant for your 1ml Cartridges to not stick out too far.
