This is a brand new, size 100, long-sleeved pajama set for boys. I bought it for my son, but he outgrew it before he could wear it, so I'm sadly selling it. It has a cool dinosaur print and looks awesome! Although the temperature is rising, it's still chilly in the mornings and evenings, so how about a set? You can use it for two seasons: spring and autumn! I can ship it the next day via Rakuraku Mercari. Thank you.
