Positives:
- They are not toxic.
- The colors are pretty.
- They are washable if they were used on a plastic or wood surface.
- Negative points:
- They do not go so easy: in small hands.
- Since the mine is also back, my little boy of 21 months can not always write with, according to the way he holds them.
He loves them anyway because at the moment they are the only it can use.
- The plugs are difficult to open and close (I do not know if this is intentional or not). They are not easy to reseal as both ends have holes so the child is wrong and does not understand why he can not close itself. These are details but a little of that age who wants to do everything alone, it can get very frustrating.
In conclusion: no top. After those, I'll buy another brand.
