Thank you for viewing. This is a Didymos baby wrap (baby carrier) from Familiar. Size 5 70cm x 420cm Approx. 570g Material: 100% cotton I purchased this from Familiar at a department store about 10 years ago and have only used it 2-3 times, then stored it. There is some slight wear and tear, but I think it can still be used. Please refer to the Didymos website for instructions on how to use the Didymos. https://didymos.jp Thank you.
