Thank you for viewing! Long-sleeved pajamas, size 150 cm, purchased from GU. These are cotton pajamas with a cute animal pattern. They are comfortable on the skin and made of 100% cotton, so you can wear them year-round, except perhaps in the peak of summer. There is some discoloration on the arm area, but it's not very noticeable due to the light blue fabric. Please refrain from purchasing if you are concerned. The elastic in the pants has been replaced once. It's a thick green elastic, but please replace it if you don't like it. Thank you. - Brand: GU - Size: 150 - Material: 100% Cotton - Design: Animal pattern (polar bears, rabbits, etc.)
