We have these pins with two daughters for years for classroom instruction. They can sharpen easily and break them as opposed to cheap pens from not constantly. In addition, they have good color intensity. The only downside to the story is that the pins are relatively expensive. We have otherwise bought here in a stationery shop always on site, but there the pins should now fewer than 18 EUR cost, which I then but seemed a little immensely, so I've been looking for lower-priced offerings. The offered price here seemed acceptable. For good pins you have certainly grab even deeper into their pockets.
