Staedtler 309 handwriting pens are specially designed to promote correct handwriting position. The hardwearing plastic tip withstands pressure and provides resistance against paper to encourage more comfortable writing. The moulded grip zone ensures comfort and extra control when writing. The pen features a ventilated cap for safety and a pocket clip to prevent the pen from rolling on or off the desk. These pens feature the Staedtler dry safe ink which means that the pens can be left uncapped for days without drying up (Test ISO 554). The ink is also ultra washable so can be removed from textiles easily. This pen has a medium line width (0.6 mm).
