I don my have a label or much info on these. They are a good fit for my 10yr old so the age range in estimated. I see most goggles for this brand list goggle size 6-14yrs so it’s possible this is the same but I think 8-12years is a much safer estimate. Have taken pictures of bobbles in the elastic. There is some very minor scratching on the lenses which I couldn’t capture on the pictures very clearly but have tried.
