Nice product - Lyman Scale Weight Check Sets

This is a really nice product and I would consider calibration weights a 'must have' for any reloader. I realized that my powder scales were off by a few tenths of a grain. The only complaint I have on this product is the cruddy tweezers that come with it. I've dropped some of the weights a few times trying to handle them with the tweezers. Also the foam insert makes it hard to remove and replace the weights especially using the tweezers. Overall though it's a nice set of weights.
