The markers are intended for our almost 4 year old daughter. They have a good price / performance ratio, paint well and meet your perfect destination. Due to the sometimes uncontrolled imprint they fray over time, but that is probably not the markers themselves. One point deduction is available for the lid. As described in other reviews this has two openings and harbors, the risk of destroying the pen, if you take the wrong opening by mistake, what often is the case with children. So far, however, no total failure of the head itself. I would buy the pins again.
