I fell in love with this ring and bought it at a department store pop-up about a year ago, but I treasured it so much that I never used it and kept it in storage. It's incredibly cute. The inner diameter of the ring is about 1.6cm. I would appreciate it if you could understand that it has been stored at home. I used a different box to take the photos. I will send it to you in the drawstring bag it came with when I purchased it.
