Matters Needing Attention:
1. When drilling, it should be vertical, Don't push too hard, Slowly twist the needle toward one direction, the needle should not be broken by force Don't pry, otherwise it is easy to be damaged!
2. Do not clip it on the electric hand drill to drill holes at high speed, otherwise the amber will collapse.
3. Pay attention to cleaning the surrounding powder while rotating.
4. Hold the end of the drill bit by hand and rotate it slowly to drill. When it is about to open, pay attention to reduce the speed and strength.
5. If you feel that the needle is tight when rotating, Please withdraw the needle, After cleaning the hole, the powder is not re entered!
