These needles are 42 Gauge with 3 barb on them, each separated in different places on the triangle shaft. These needles will take a few hairs in on each application so good for starters as you learn to root the hair. The needle is a fine triangular shaft and you will find 1 barbs on each side. You will receive 10 needles. If you require the rooting tool I also sell them as well in my store under tools.
I have sourced a very top quality product which you are sure to love. If you have any questions please do not hesitate to contact me
