This is a Neo Mamaism winter sleeper with padding. I received it at the end of the year, but it's too warm for my home environment, so I'm selling it. I put my arm through the sleeve once when I received it, but I haven't used it at all. Navy sleeper with a cute constellation pattern. - Color: Navy - Design: Constellation pattern - Award: 2024 Kids Design Award - Features: Padded, detachable sleeves - Usage: Winter sleeper According to the official website: "The zipper at the feet allows for longer use, even after the recommended age. Even a 3-year-old (90cm tall) can wear the L size (recommended age at purchase: 12-18 months), and the length is just right for walking." As stated, it seems like this item can be used even as your child grows a little, thanks to the opening at the bottom. I have the box, but it's a little torn, so I plan to ship it without the box unless the buyer requests it.
