It seems blocky. It corner cuts but not the best. No spring noise. Not sandy but it is a dry feeling puzzle. I wouldn’t consider the shades as being neon. They are pastel. I don’t like the shades. They are very dull which is the complete opposite of neon. I gave it a 4 out of 5 stars though because the price reflects the quality and you shouldn’t expect much more. At the same time I expected brighter shades.
