Specifically designed for use with the Wacom Bamboo Stylus Feel for Samsung Galaxy Note or Wacom Bamboo Pad (USB or Wireless) stylus, Bamboo Pad Nibs slide easily into the barrel of your pen, replacing used nibs. With a stiffer feel, similar to a ballpoint, it offers precision without scratching the glass surface of your tablet. Each package includes five, black firm nibs, 23mm in length.
