I bought these because they are environmentally-friendly and non-toxic - very affordable for a "specialty" product like this. While the box does have 16 crayons, many of these are duplicates of the most commonly used colours, which is great. I did find that the crayons "flaked" a bit - kind of like little bits of eraser. I don't remember other crayons doing that the same way - but easily brushed off the drawing. That's the only reason I'm giving these a 4 out of 5. Otherwise very happy with the purchase.
