These are a triple strand build, not a single piece of silica. Each coil has 3 pieces of silica rather then a single piece.
For the lazy people like me - this is a great deal. You get 10 pre made coils for only $2.79. It also includes a little plastic holder. These are made of regular resistance kanathal wire with silica wicking. Meant to work in all standard RBA's.
Each coil is 1.8ohm
For the price and convenience you cant go wrong.
