NexMESH OFRF mesh coil outsmarts the regular coils when it comes to flavor production. There are two varieties of NexMESH OFRF mesh coil available. These are Kanthal A1 NexMESH Mesh Coil and SS316L NexMESH Mesh Coil! Intricate micro-weave netting offers a greater surface area. This produces a better flavor experience because of the even heat distribution.
