This appears to be a quality set. I’m not a regular baker or anything so the 3 sizes are perfect for my needs. The bowls aren’t too heavy nor too light; actually just right. The lids are plastic with a decent thickness and push down to rest inside the lip of the bowl rather than along the top edges which seems more secure. The bowls nest within each size, but without the lids attached. They are very shiny on the inside and a bit more frosted or matte on the outside. I like them.
