A creative art pen specially designed for "ink free rubbing" can instantly transfer the texture of coins, leaves, reliefs, Braille and even PCB copper foil to paper. It does not need paint, does not dirty hands, and is safe and environmentally friendly. It is suitable for children over 5 years old, art students, designers and manual players. The pen tip is made of high-density microporous felt core and ultra-fine graphite powder bag, which can release graphite particles evenly with light pressure, forming a 600 dpi level detail restoration. Rotate the tip of the pen to replace it. Applicable scenarios: Parent child nature class: rubbing different leaf veins. Industrial Design Course: Quickly record hand board reliefs and button textures. Hand account: Collect travel commemorative medals and antique copper coin textures into the hand account.
