Box has been open but it is new, unused. I ordered this crib-to-toddler bed conversion kit for my son’s bed in the fall and we finally went to switch it over a few weeks ago and I realized it was the wrong model. Unable to return. https://www.westelm.com/products/mid-century-crib-conversion-kit-only-h11312/ This fits the West Elm Mid-Century Convertible Crib (Mid-Century Convertible Crib, Acorn, WE Kids https://www.westelm.com/products/mid-century-convertible-crib-acorn-h3207/?cm_src=SocialShareLink&sku=9505930)
