Some items may have scratches. Thank you for your understanding. This is a smartphone holder that can be attached to bicycles, motorcycles, etc. Nowadays, you can use high-performance maps and navigation systems with just your smartphone. However, it's dangerous to hold it with one hand. That's why you need a holder. This holder can be attached as shown in the image, and the angle can be adjusted. Moreover, the way it's fixed is not just by clamping, but by holding the four corners, so it probably won't fall easily. You can also attach it to a stroller for safe outings. The installation method is shown in image number 8, so please take a look.
