I have cleaned these at home. There is a main pair of indoor shoes, and these were only worn occasionally, so I think they were used a few times at school. They are not new, so there is some yellowing and dirt, and they show signs of use, but they are generally in good condition and can still be worn. There is a name written on the heel, so I have put a name sticker over it. I peeled off a name sticker from the instep, so it's a little fuzzy there. When shipping, I will pack them so that they are thin enough to fit in a post box, which will involve crushing the heels. These are used items that I have inspected as a private individual, so please understand this. Thank you.
