Is that what they wrap the atomizers in? The metal mesh?
Yes,,,I believe it is Nichrome Wire they use for Attys some manufacturers may use different types, but if you use ss 400 mesh the flavor you get will be even better in the Sapphires, there are also other types of Wicking material that are much better as well this =http://www.omega.com/ppt/pptsc.asp?ref=XC_XC4_SLEEVING XC4-116 being just some super stuff ! it does not burn at the temp we operate with, I've been using both together on some things I'm projecting on and the flavor is like nothing I've ever had before with my
juice, and just plain ss 400 Mesh as the wick in those Sapphires is super, you need to roll a real tiny thin piece of it and slide it in where the wick goes in place of what your using. You can
buy the stuff at the mesh factory or McmaterCarr dot com.
