You can find this on Kamry site. The call it the Kick but it's only a fuse.
For the un-experienced vaper - this is NOT "that" Kick you can use to adjust your Voltage. It's only a safety fuse that will protect your battery from short circuit in mechanical mods. Safety fuses are good to have and you can by various types at most vendors.
