Ja'i two son (7 and 3 years) and I'm childminder, so much that these markers do not really idle !!! Well, they are highly resistant (the tip does not sink and does not collapse), vibrant colors and they are easy to clean (Therefore, I have no complaints from parents). My 7 year old son uses it in two ways: the tip to the side for drawing and coloring. Very good price / quality ratio! I recommend it.
