This is a set of Shinkansen (bullet train) and locomotive items. The white T-shirt is thin. The other items are fleece-lined sweatshirts. The size is labeled as 90, but it feels like a size 80. My son is currently exactly 90cm tall, and it feels small on him. The white T-shirt has stains on the neckline and cuffs that won't come out. Also, the name is written on the tag, so I will black it out before shipping. The tag on the green locomotive sweatshirt was cut off when I received it as a hand-me-down. The Hayabusa (bullet train) and locomotive sweatshirts are prone to pilling. I've removed as much as possible, but some small pills remain. The sweatshirt with three Shinkansen trains lined up has buttons at the neckline. This one is less prone to pilling. These items have been used. I hope someone who understands this will purchase them.
