Thank you for viewing. I purchased this three years ago for my child's baby carrier and used it a few times. ☺︎ My child didn't sleep easily, so I wanted to use something easier and less bulky than an Ergobaby carrier for nighttime sleep, and I bought this. It's size 2. I have the box, but I've lost the rubber band that bundles it. If you don't need the box, I'm willing to lower the price, so please let me know in the comments. There are no smokers or pets, but it has been stored at home, so please understand.
