Cotton 100% Baby Sleeper Star Pattern [Set of 2] Due to shipping costs, a single item is slightly more expensive, but it can also be sold for 888 yen. It has a double zipper, so you can also let the feet out. Used for about 2-3 months. I washed it in a laundry net, but there is some wear and tear, and some minor fraying. It's a fairly thick type, and I didn't get to use it much because I missed the season. It's perfect for this winter season. It's a type where the hands can come out even when the baby rolls over, and the feet can also come out, so it's also recommended for graduating from full-body swaddles. You can basically use it as long as the baby doesn't outgrow the width. If the baby stands and steps on the clothes with their feet, the shoulder buttons may come off a little, and the snap buttons don't seem to be very strong. In my personal opinion, it's recommended for babies around 6 months old.
