This is a lightweight baby carrier made of breathable mesh material. It's perfect for babies aged 0-3 years old. A friend purchased this about 7-8 years ago and gave it to me. I used it for all three of my children. I started using it when they were about 2 months old. It shows signs of use, but it's still in good condition and can be used! *Please understand that this is a used item before purchasing. *There is no instruction manual or box, only the carrier itself. - Brand: BABYBJÖRN - Color: Gray - Material: Mesh - Features: Adjustable straps - Size: For 0-3 year olds, 3.5kg - 15kg - Weight Limit: Up to 15kg - Model: Baby carrier, back carrier, forward-facing carrier Thank you for looking.
