I received these new, but I haven't had much chance to use them, and my child has outgrown them. Socks size: 7-9cm The socks don't appear to have any stains, but some have some fuzzing. All items have been washed with the same detergent as adult clothes, so if you are concerned, please wash them with baby detergent after purchase. Also, please understand that all items have been stored at home for several years after purchase. (Non-smoker, no pets) I have two small children, so I have set the shipping time with some leeway.
