This kit uses PockeX Coils available here.

Simple, discreet and effective. If this is what you're looking for in an e-cigarette then look no further! The new PockeX from Aspire combines a 2ml, top-filling, leak proof tank and 1500mAh battery into a package no longer than an average cell phone, making it perfect for on-the-go use. With coils based on the popular Nautilus X "U-Tech" design this tiny go-getter delivers all the vapor production and flavour you could ask for without the battery drain of higher wattage devices. Once you get this little guy in your purse or pocket you'll never want to go back!
