As Seen on Miracle Copper Socks, Copper-Infused Compression Socks Large,  2Pcs

Works well, easy to use. I checked scale with gram weights from .5 gram to 100 grams and all spot on. Note the latch is a push in type! Do not try to flip it open without pushing latch in! I use this to measure Matcha tea, which is very expensive, The other weights I did not check. Also I use a small measuring cup without a handle that weights 35 grams then I use the tare function that sets the scale to 0 and can weigh only net product. Hope this helps somewhat.
