I am impressed with this dual_laser, a 10w diode laser and a 2w fiber laser. You can engrave on almost all materials, the wood, the leather, the stone, the plastic, the metals, and etc. Besides, the newest accessories are also amazing. The rotary extension can engrave on cylindrical object, even inside the ring; the slide extension can expand the engraving area，also you can have fun with multi_layers.

Don't forget to wear the protective glasses or shield when you use a laser.
