It is not the quality of the needle, but the needle is too thin. If the bearing force is small and the force is not correct, the needle will break easily. It is recommended to buy more needles, especially for the rude novice affinity. It is recommended to use the 0.8mm needle, but as long as the needle head is constant and the needle bar is broken, you can continue to use it, without affecting it! The 0.6mm needle is suitable for planting small heads of 6 points and 12 points. The 0.8mm fork is quite suitable for big dolls like salons, and it is also relatively hard! Novice suggests skipping the 0.8mm needle! 0.6mm and 0.8mm needles have lengths ranging from 2.5cm to 3.5cm
