The finest micro-rooting needle anywhere, they can easily be cut with wire cutters or small bolt cutters to fit the wooden mushroom handled tools, or they can be used intact in any of the other rooting tools I sell. Excellent for rooting soft vinyl OR silicone. They are reported to be super strong and if you work with a well-heated vinyl head, they will bend but not break if you're careful. Yes, it's slow going but the results are worth it. These needles are demonstrated by Cassie Peek and Rachel Maynard in their Hair Rooting DVD.
