Usually, young children unable to apply the correct amount of pressure irretrievably push the tip of their pens into the shaft. These markers feature a spring-loaded fibre tip which disappears into the shaft in case of too much pressure and returns once the pressure ceases. This allows children to learn to gauge pressure accordingly and trains their fine motor skills. The organic shape of the pen offers a pleasant feel. The coloured inks correspond with statutory regulations, and the ventilated cap ensures that the child can breathe enough air should the cap be swallowed.
