The Eclyp Omni Mark II is a pocket clip for your tube or box mod! Using a 510 to 510 adapter, the clip fits between your tank/rda and your mod. Works with most mods. Not recommended for temp control and hybrid.
When you purchase the Omni Mark II, you will receive a new adapter. We had this adapter manufactured to our specs, and it is so much stronger than what we were ordering before!
