This is the Smolvy "Lightweight Sleepy Baby Carrier Mesh Summer"! The color is charcoal. Used only a few times, and I think it's in very good condition! It can be used from the newborn period as it comes with a head support, and the belt is easy to adjust, so not only moms but also others can use it right away. The mesh material is breathable, and it's also good that it dries quickly even after washing! Babies are very warm (hot when being held), so mesh is recommended all year round. The auxiliary belt also serves as a storage pouch, so you can store it neatly and compactly even when you're out and about. It's a beautiful item, but it is a used item, so please refrain from purchasing if you are sensitive to this. Instant purchase is OK!
