This is a Sunkmamiere baby carrier. It's a type without a waist belt and can be stored compactly, so I used it separately from another baby carrier. There are no noticeable stains, but please refrain from purchasing if you are sensitive to used items. No instruction manual. Head support included. How about it for a second carrier or for those who want to try it out? ⚠️Please be aware if you have allergies, as I have a cat.
