This is a BB Grant Energetic High Socks (new, unused). I purchased two sets in June 2025 and used only one set, so I am selling the unused one. The purchase price was 12,000 yen for two sets (approximately 6,000 yen per set). It has been stored in a closet. These socks are helpful for those who sit for long hours, those who experience leg swelling during air travel, and also for pregnant women. Size: M (23-25 cm) Denier: 520 Thank you for looking.
