Are you a builder? Do you like to try out different coils on your RDA without the massive cost of pre-coiled packs?
Steam Shark has built a reputation for great quality at reasonable prices. We even use it ourselves, for our personal builds!
Kanthal has a higher resistance than most other metals, meaning you can get great output at lower wattage's, and it's excellent for building safe and sane coils on Mech mods. Long lasting, and easy to keep clean.
Why not give it a try? You wont be disappointed.
