Flex-rite is very fine stainless steel wire coated in clear nylon. It is extremely strong and is excellent for heavy projects or where the beads may abrade the thread. The 21-strand type is more flexible than the 7-strand but less flexible than the 49-strand. The "clear" style allows the silver colored stainless steel wire to be visible.
