About This

• ‌【Engraving Bit Set】‌This set includes 30 diamond grinding heads and 1 K-needles, both made of diamond abrasive material. They can be used for engraving patterns or text on various surfaces such as glass, metal, jade, ceramic, and other flat materials. Some practice may be needed initially for better results.
• 【Note: Due to the oxidation process in the manufacturing of the diamond abrasive, you may notice slight rust marks on the handle of the grinding head. This is normal and does not affect performance—it is a result of the specialized oxidation technique. Once inserted into the engraving pen, it will function perfectly.
• 【3 Adjustable Speed Levels】‌This mini engraving pen features three adjustable speed settings with stable rotation, suitable for different materials. Its compact and portable design makes it easy to carry around, letting you enjoy a relaxing time of handmade art.
• 【Portable Charging】‌This engraving pen is rechargeable and comes with a USB charging cable. Once fully charged, it can be used wirelessly for up to 30 minutes, allowing you to complete your engraving projects with ease and enjoy a sense of freedom.
• 【Smart Power-Off Protection】‌It has a built-in safety protection circuit board and a smart overload protection chip. When the working resistance is too high, it will automatically cut off the power to prevent damage to the electric engraving pen.
