Drawing pin made of metal is difficult to take out once inserted into the wall. In most cases you have to use your finger nails to dig it out, and this may hurt your nails. Humanisitic design of easy-pressed pin set it apart. Made of rubber, easy-pressed pin can be turned over easily just like girl’s skirt. Press it first, and you can pull it out without difficulty. The pins pressed if not pulled out can mark something prominently.
