Thank you for looking! The gray items are new, and the others have been worn about twice. Since they were worn during a time when the child wasn't walking, I think they are in relatively good condition, but please understand that they have been washed and stored at home before purchasing. The long socks look black, but it's due to the lighting. There are no stains, and the overall color is beige. I apologize that I don't know the size because there's no size indication, but I think the two shorter ones are about 9-12 cm. The longer ones seem like they can be worn a bit longer.
