As mentioned at the beginning, please note that it cannot be transformed into an open panel form. ■ Items for sale "Device (Closed Form Fixed ver.)" Photos 1 and 2 are the actual product. ■ Overall length/Weight Approximately 14cm, 1 device weighs approximately 50g (much lighter than a smartphone) Although it is new, it is a handmade item, so please refrain from claims or returns except for damage/abnormality upon arrival. Immediate purchase is OK. Please comment if you have any questions or requests. ★ Handling ★ The item's strength is stronger than resin, but it will break if dropped or subjected to strong impact. Forcing thick cords or metal into the strap holes will cause it to crack. Please be careful when handling, as it may deform if left for a long time in a high-temperature environment, such as a place exposed to direct sunlight like the summer sun or the inside of a car in the scorching heat. ★ Attaching to costumes ★ As shown in photo 3, it is convenient to combine it with various straps by attaching the "U-shaped parts". You can use the attached strap or use another key ring. Once you have decided how to attach it, glue the U-shaped parts to the holes in the device body to prevent them from falling out. ★ About the product photos ★ Regarding the color, the color may differ from the actual product due to smartphone app photography. We can provide additional photos for confirmation.
