This is a set of brand new, size 100 long-sleeved pajamas for boys. I bought these for my son, but he outgrew them before he could wear them, so I'm sadly selling them. They have a cool dinosaur print and look great! Although the temperature is rising, it's still chilly in the mornings and evenings, so how about a pair? They can be used for two seasons: spring and autumn! I can ship them the next day via Rakuraku Mercari delivery. Thank you.
