I would say this is pretty accurate -- these are really nice cups. the instructions are not very detailed, but if you are buying an expensive C&B set like this, you probably have other sources for your routines. The aluminum cups are not as heavy as the brass or copper, but these cups are a bit heavier than most of the aluminum cups on the market. They handle nicely.
These are the ALUMINUM set of three cups and four crochet balls, with carrying bag. These typically retail for $38-$44. get 'em here for less!
Brand new, with instructions.
