Before buying these rods I already watching the reviews that's why I give it mien.Moi I bought for my son who is 2 years old and he plays every night with lots of fun and it s. The +++ I find that they do not melt easily in the water, my son when he finished with a color it leaves it in the bath water and when I vacuum pencils n have not melted. It is simply cleaned with a sponge. --- When the tiles are wet or bath that no longer cries. But I am very satisfied plus it's cheap, but shipping is more expensive than pencils
