I had been looking for an rba deck for Ijoy subohm tanks (specifically Diamond, Captain X3, Katana, Avenger) and only finding overpriced ones like at Element ($7.95 for one deck + $7.95 shipping). And they are about the only place that currently has them, until I stumbled on this deal. Not only are they $3.99 + $5.00 shipping, you get a 3 pack!! This seller is having a sale right now, so might even be less. I placed order a few days ago and they came today. They are single coil RBA's. Have not used them yet, but checked fit with my Ijoy tanks and they are right on.
