later A few complaints about the price. The container is cheap of course, but you don't really buy it out of the box, it's strong enough and stays closed well. I measured the number of mine with precision calipers (certain use required a 0.5mm shim) there were slight variations but most were within 0.05mm of each other. The size of the largest spacers (3 obtained) ranged from 1.97 to 1.96 mm, all subsequent ones were within 0.02 mm of 1.75 mm (5 obtained). I bought this set for 0.5mm spacers and they were all slightly under 0.45mm and 0.48mm. Close enough for my use case. The smallest size is 0.1 mm, there are about a dozen of them. Overall a good choice for the price. The only real complaint is that a couple of the pads have discolored a bit. Also stubborn stuff, strong alcohol and scrubbing didn't even remove it. I will not refund money for this, most were in perfect condition.
