Thank you for viewing! This is a popular Shinkansen (bullet train) series for boys. How about using it to prevent soiling at kindergarten, nursery school, or lessons? The main body is made of oxford fabric, and the sleeves are made of sheeting. It allows for easy arm movement. Size: 100cm (Measured flat, the length from the back neckline to the hem is approximately 42cm, sleeve length from the underarm to the cuff is 27cm, from the neckline to the cuff is 41cm, and the body width is measured under the sleeves at 42cm). The elastic in the neck and wrists has openings so you can adjust the length and replace the elastic. It has a hanging string and two pockets. Made with an industrial sewing machine and a serger. I make them with care, but they are handmade by an amateur, so please understand before purchasing.
