New cotton pajamas with a blue, green, and white check pattern, embroidered with a Shinkansen (bullet train). New. - Brand: SHINKANSEN - Color: Blue, green, and white check - Size: 80 - Design: Shinkansen embroidery - Material: Cotton Thank you for viewing. I bought these for my child, but they outgrew them without using them. They are long-sleeved, but there's a button on the sleeves, so you can roll them up and make them short-sleeved. There's a button on the side of the pants to prevent them from slipping down. There's a button and string on the waistband of the pants. The pants are long pants. I think they can be used from spring to summer. They are new, but there is a yellow stain at the marked spot.
