I have some replacement fiber in packs and loose in various sizes and colors. This is acrylic fiber that is very flexible- not brittle. It is also brighter than a lot of the other fiber I have seen. I have 5 packs of .019 with a piece of Red, Green, Blue, Orange, and Yellow each cut to 12" for $15 TYD. I have a few 5 packs of .029 with a piece of Red, Green, Blue, Orange, and Yellow each cut to 12" for $15 TYD. I also have a some 12" pieces of .010, .019, and .029 fiber in the colors above for $4 each TYD. Five or more pieces is $3 each TYD. I prefer Paypal, but will accept MOs. I do have a limited amount right now, so please check with me for availability before purchase. I am also working on getting some fiber that will work great at short lengths (less than 4"), as well as some more choices in .010 fiber. If you need anything specific as far as lengths or quantities, let me know and I can probably arrange it. Also, anyone outside of US please PM me for shipping charges. Thanks for looking!
