Thank you for visiting our shop! (*^^*) This is a key ring hanger. You can attach keychains and straps to your smartphone case with it☆ It's silver, so it should match your smartphone easily (*^^*) Since it's a set of 2, you can use both to attach straps, or use just one to attach a keychain☆ Double-sided tape is attached to the back. This is an imported item. I have taken it out of the bag to check the condition when listing it. The photos are of the actual product, but the color may look slightly different from the photos depending on the lighting. Please refrain from purchasing if you are concerned about this. If you have any problems with the product upon arrival, please contact me before leaving a review (*^^*) I am also selling on other sites, so I may delete the listing without notice.
