Thank you for viewing. Purchased from petit main. Size is 100. It's a fabric that's between a long-sleeved T-shirt and a sweatshirt. It's not too thick, so you can layer it underneath or wear something over it, and I think you can wear it for a long time. ※ Photo 7 There is a stain-like mark if you look closely. ※ Photo 8 It's on the inside, so it's not visible from the outside, but there's a place where the white backing fabric is peeling. Other than that, there are no noticeable stains, but please understand that there may be oversights. This is a used item. Please understand and purchase. I will fold it as small as possible for shipping. ◯ There are no smokers in the family. ◯ I do not have any pets. #Petitmain #Long sleeves #Dinosaur #Boy #Kids #Autumn and winter #Cut and sew #Bundle sale #Petit main
