Slowly twist the hole in one direction by hand.The needle cannot be broken or pried,otherwise it is easy to damage. 2.It cannot be clamped on a hand drill to rotate at high speed.This way the amber will collapse. 3.For the punching type,please pay attention to clean the surrounding powder while rotating. 4.Grasp the tail of the drill bit by hand and slowly rotate and drill.When it is about to get through, pay special attention to reducing the speed and strength. 5.If the needle feels tight when it rotates,please withdraw the needle and clean the hole and re-enter the powder. The positioning ring has multiple colors and is assembled randomly, so there is no guarantee that the color of each box will be the same.Please refer to the actual product.
