I had these custom-made because the store-bought ones didn't fit the daycare's specifications, but I'm selling them now because my child is transferring. The fitted sheet covers were used alternately (about 9 months), so each was used for about half that time, or 4.5 months. The duvet cover was used for about 4 months, only during the colder months. Both covers had name tags sewn in the center, so there are small pinholes where they were removed (see photos). * Light blue fitted sheet cover: Backing broadcloth (light blue) Buttons: 5, light blue * Blue duvet cover: Backing broadcloth (light blue) Buttons: 4, navy blue The sides have snap buttons instead of zippers, as per the daycare's requirements. They're still in good condition, so if you're looking to save a bit on custom-made items, why not? (Original price: 5,530 yen) Please feel free to ask any questions in the comments. ^^
