This is a set of a smartphone shoulder strap and a strap holder. It easily attaches by simply inserting it into your smartphone case, freeing up your hands, which is convenient. Although it's unused, I opened the package, so I've marked it as "like new." Please refrain from purchasing if you are sensitive to items stored at home. [Colors] Black, Pink, Black x White [Materials] Polyester, PVC [Other] Adjustable length Thank you.
