☆ It's sweatshirt material, but thinner than typical sweatshirt material. It's a cool design, so I recommend it as a T-shirt. ☆ Size is American size 5-6 years old (approximately 110cm in Japanese size) ☆ The design on the pattern is three-dimensional and cool (^_^) ☆ There's a faint stain (I've included a photo). Other than that, there's nothing to be concerned about, but please understand that this is a used item before purchasing.
