Vaporesso Gen Mod with skrr-s, o rings?

[vapejunky]

• Just found my tank leaking, i worked out I lost my o ring. Just wondering if anyone knows where I can get them online. I found the spairs that came with the tank but I just want to get some more before I lose the spare. Ive ordered the bigger bubble glass which comes with o rings. Just dont want to have to keep buying glass when I only need the rings. Thanks
