I was shocked to receive 12 pairs (!) of these knee-high stockings - two packs of 6 pairs in each! They seem durable enough, I have washed them 3 times already, and most of them are still in perfect condition. The material is pleasant and sheer. But regardless, 12 pairs for $8.50 is unbelievable for such nice quality knee-highs. I will be buying them again once I go through these.
