These are Gunze, est, and douxblend brand stockings. The est ones are 7-part length, while the Gunze and douxblend ones are full-length. I found these while organizing my parents' dresser, and since I have no use for them, I'm putting them up for sale. I've stored these for a long time after purchasing them, so although they are new, I opened them to inspect them. I didn't see any noticeable stains, but please forgive me if I overlooked anything, as I am a private seller. I hope someone will find these useful in the coming cold season.
