Ergobaby, a cotton infant insert! I only used this once or twice as I mostly used a stroller. There is a light stain on the back. I will dispose of the box and ship it flattened to fit in a post. If you need the box, it will be shipped via courier, so please let me know and I will add 500 yen for shipping. - Brand: ergobaby - Model Name: Infant Insert - Material: Cotton - Color: White - Condition: Slightly dirty Thank you for looking.
