BabyBjorn babybjorn one kai air Silver I have both an Ergobaby and this one, but I've been using the Ergobaby exclusively, so I'm selling this one. I mainly used the Ergobaby, so I haven't used this one much. I think it's in good condition, but there's a faint stain. Please check the pictures! I'm also including a baby carrier cover! It's made of a fleece-like material and covers the baby's legs completely, so it looks warm(^^) Please refrain from purchasing if you are concerned about minor details, as this is a used item!
