I purchased this about two weeks ago. It's a set of two items, but I don't plan to use this one, so I'd like to give it to someone who will! I plan to ship via Yu-Yu Mercari Delivery, but I will discount it by 50 yen if you prefer standard mail. Please let me know in the comments before you purchase if you'd like this option ⸜( ˙ᵕ˙ )⸝ I bought it as a smartphone strap, but I think it can also be used for keys.
