These pens are really the best thing there is to crayons for very small hands in the market. My daughter got these pins to their 2nd birthday and also paints today (4) still prefer them. They can be kept well by its thickness, are as good as unbreakable, are very strong in color and are easy to paint, especially on large surfaces. You also paint on dark paper and allegedly at the window (not tried), can be personalized with a water brush like mascara Vermalen (looks great) and can easily wipe off the table and wash out of clothes - just the purple pin is a little stubborn. Two criticisms there anyway: Young children like to suck times a pen - that's when these pins a medium-sized mess - both on the face as well as clothes and furniture. In addition, the pins have to often be tipped - thus they wear out quickly because the air does not reach to the end of the pen. In spite of this: The - and no other!
