Thank you for looking ^^ This is a handmade smartphone shoulder strap knitted with colorful yarn. It's an easy-to-use item that can be easily paired with simple outfits as an accent. After completion, I used it myself several times, but I don't see any noticeable stains. It comes with a metal clip, so you can attach it to your existing holder. Please understand that this is a handmade item by an amateur, and there may be some imperfections.
