My child wore these. Selling because they've outgrown them. Size: 140cm, suitable for ages 9, 10, and 11. The color is blue-系 (blue-toned), the waist is elastic, and the material is like a jersey or sweatpants with stretch. They've been used, so there's some pilling, but I plan to sell them as-is. I've inspected them, but it's a casual inspection. I've checked to avoid any major oversights, but please forgive any small oversights. These are used items. Thank you for your understanding! For anonymous shipping, I may change between Yuu Yuu Mercari and Rakuraku Mercari after purchase. Please let me know before you buy if you have a preference m(_ _)m Kids, pants, trousers, 130, 140, 150, boys, pajamas, winter, warm
