Excellent condition Baby Bjorn ONE KAI AIR BLACK baby carrier. I used it to take my eldest son to and from daycare. I only used it for short periods for about two weeks, so it has little wear and tear, and I think it's in good condition with no noticeable stains, scratches, fading, or deformation. I think you can still use it comfortably. I've taken detailed photos, so please take a look. Everything in the photos is included. Cleaned at home. I didn't use it on rainy days. No pets, no smokers. Please understand that this is a used item. Material: Breathable 3D mesh material that dries quickly after washing. Features: Ergonomic design with four carrying positions (facing in before neck control, facing in after neck control, facing out, and back carry). Features a sliding function that allows you to put your baby on your back by yourself while standing. Designed for long-term use from newborns (3.2kg) to approximately 36 months (15kg). Recognized by the International Hip Dysplasia Institute for its hip-friendly design.
