We have already fallen off the crayons a few times and not broken. In addition, it is quite normal that crayons and break times, even the expensive Pelican etc are not protected before.
Jumbo they are not really, but thicker than normal crayons definitely. You are my daughter (3) very well in the small hand and she paints really love it. Me too.
The color quality is perfectly fine for a good price. Beautiful and many colors.
Can Tell I definitely and would also buy more again.
