Purchased on Rakuten in October 2024. It has been worn many times, so there is a feeling of use, but there are no noticeable stains. Washed with Arau Baby unscented detergent. Size: L: 8.5-11kg / 6-9 months Pattern: Sea Forest (hand-out type, all seasons), Dream of Space (hand-out type, all seasons) They were a great help! I used the hand-out type after the baby started to roll over!
