This rehairing tool is what I use when putting new manes into my little ponies. Each one comes with two rehairing needles. Additional needles may be purchased at $1.00 each. Each tool is shipped with instructions on how to use it. The needles are all hand cut and sanded to remove and snags in the metal.
Choose between three Needle sizes when ordering.
Size 20, Size 22, and Original. Please see pictures for size comparisons.
Original is what I personally use for every custom that I make.
