Aya Aiba's Swaddle Sleeper for Summer Purchased here in September 2024 Used once, but didn't suit my child, and has been stored at home since. Washed with Arau Baby unscented detergent. The previous owner purchased it in June 2024 and wore it about 2-3 times. There are no noticeable stains or pilling, but please refrain from purchasing if you are concerned. I think it can be used even when it gets chilly if you adjust what you wear underneath. Retail price: 8,980 yen
