These Tech-Protect Stylus Tips provide a reliable replacement for your Apple Pencil, ensuring a consistent writing and drawing experience. Each set includes four white tips compatible with the 1st Generation, 2nd Generation, USB-C, and Pro models. Constructed from a combination of copper and POM, these tips balance electrical conductivity with long-term durability. The copper core efficiently transmits the necessary signals for operation, while the polyacetal exterior acts as a wear-resistant engineering material that maintains stable contact with the screen. Measuring 12.40 x 5.00 x 4.00 mm, they fit securely using a simple screw-on mechanism that requires no additional tools for installation.
