Last year, in July 2023, I purchased two of these at the Tower of the Sun Museum Shop at the Osaka Expo, one for each of us. However, we realized that the models we own are different, so we haven't used them. We liked the design, so we kept them as display pieces, but we won't be using them in the future. If you are an iPhone 12 or 12 Pro user and a fan of Taro Okamoto and the Tower of the Sun, I would be happy if you would consider purchasing them.
