Thank you for viewing! m(_ _)m Baby Carrier ONE KAI Air BabyBjorn Baby Carrier/Sling Retail price: 23,760 yen Color: Gray Purchased in the spring of 2023 and used for six months. I don't think there are any stains or noticeable dirt, but please check the images for details. Can be used from newborns. Stored at home for a long time. Please understand and purchase. Instruction manual is not included. The good point was that the neck didn't droop back even when the baby fell asleep. Of course, it was useful in the summer, and it also got surprisingly stuffy in the winter when wearing thick clothes, so the mesh material was helpful. Thank you for reading to the end!
