I used this from newborn to around 5 months. It was easy to put on and very useful. It was convenient for putting the baby to sleep, as I could lay them down while still holding them. I think it's in good condition, but there is some slight pilling due to friction from use. I will also send the instruction manual. Please note that there is no box. - Color: Navy Blue - Size Adjustment: Adjustable (up to 74cm) - Design: Mesh material, cross-strap design - Features: Lightweight and breathable design - Uses: Can be used as a baby carrier or sling Thank you for looking.
