These are the coils for your kanger dual coil devices. The "enclosed" coils are the newer coils from Kanger. Enclosed means the wick is not exposed like the original coil were.
We also have the new cotton coils below. However, the Cotton coils are SINGLE coils built vertically, we put them in the "dual" section because they ONLY fit the dual coils devices (yes, we know a bit confusing, but that's Kanger for you)
The "Kanger EC Verticle" coils are single coil, not dual coil.
