We have our daughter these pins for the first painting bought because the were optimal because of its thickness for small hands. You are really great, painting very vigorously although the little mouse does not have to exert a lot of pressure. They preferred these pins other pins opposite, because then you can paint much better "PARROT"! A disadvantage, however, have these pins, at least one color: The red pen can indeed wipe super of the furniture, but it remains a slight red track which no longer can be wiped away ... shame really! But otherwise I can highly recommend these pens !!
