Note
1. When drilling the hole, follow the vertical direction. Do not use too much force. Slowly twist the hole in one direction by hand. The needle can not be broken or pried hard, otherwise it will be easily damaged.
2. It is not allowed to be clamped on a hand electric drill for high‑speed rotation and drilling, otherwise it will collapse.
3. When punching holes, be careful to clean up 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 re‑enter the powder after cleaning the hole.
6.The color of the product fixing accessories will be shipped randomly.
