These are the NEW high quality needles that are capable of giving you a very small, almost invisible hole. That is where the term "Micro Rooting" comes from. When you are using these 40 gauge needles it is almost impossible to see that you are inserting one hair at a time. This needle has recently been redesigned to give it greater strength but by getting 12 at a time you will surely be able to do some additional rooting between orders. 

NEW AND NOW AVAILABLE.  THESE NEEDLES HAVE REPLACED BOTH THE REGULAR NEEDLE AND THE EXTRA STRONG FELTING NEEDLES.  I recommended this needle for all of your doll rooting projects. Same results but will help you save on the rooting of each head. I think you Ladies will like them. Try 12 of the UP's and see how you like them.
