Our engraving pen requires no installation—simply insert the bit to use and remove it after use. Three adjustable rotation speeds allow beginners to gradually learn carving while ensuring safe operation. The engraving pen features a lightweight, compact design with an ergonomic grip for enhanced comfort and precise control. Three-speed settings (5000–18000 RPM) make it suitable for various applications. Built-in overload indicator lights provide visual feedback during use. Automatic overload protection shuts off power under excessive pressure, enhancing safety. The lowest speed is ideal for safe nail polishing; the highest speed supports engraving on metal, glass, and ceramic. This metal engraving pen is equipped with a high-performance motor and a rechargeable lithium battery, charged via USB interface. Cordless operation lasts up to 30 minutes on a full charge, supporting most DIY projects anytime, anywhere.

The portable, compact engraving pen with USB charging makes an excellent gift. Includes themed stencils for occasions such as Christmas, Halloween, birthdays, Easter, and Ramadan.
