Had to pull out my magnifying glass as it's a small digital scale but it was set to pounds first time around and was .222 lbs. etc not grams. Time to get reading glasses I would say. Just weighed them all in grams now and here are the results as I got them in pairs from ali and illumn.
AliExpress
1 - 101 grams
2 - 99 grams
Illumn
1 - 96 grams
2 - 99 grams
They seem all to be pretty close and the scale does move + or - 1 gram.
