A set of felting pen and 6 needles will serve you for comfortable dry felting. You can change the needles as needed. They are triangular, with small grooves on the sides to catch the wool.
User manual: 1) The wool is processed into a soft pad using a felt needle. A felt brush or foam pad can be used as an underlay pad. 2) Wool and applique patterns are pressed gently with your fingers and punching begins with a felting pen along the contour. Make sure it is even when punching. Use the felting pen gently, do not push hard! Changing the needle: if the needle breaks, replace it with a new one by unscrewing the spring cover and continue to replace the needle with a new one, making sure to insert the new needle till the very end.
