Bandai My Hero Academia Multi Ring Jiro Kyoka BMHA-12H

This is an accessory that attaches to the back of your smartphone. Passing your finger through the ring makes it easier to hold your smartphone and prevents it from falling. It can also be used as a stand. The ring rotates 360°. Can be used with models and cases made of plastic (polycarbonate) that have a sufficiently wide and flat adhesive surface. Adhesive strength may decrease significantly depending on other materials, curved surfaces, uneven surfaces, and surface treatments.
