This is a smartphone stand that folds up compactly for easy portability. It's useful when you want to watch videos or YouTube while working, or during remote meetings. I personally find it very convenient for watching videos while cooking. The size fits perfectly in a bag, which is also a nice feature. The height can be adjusted within approximately 3cm, as shown in photo 3. Photo 6 shows an example of use, with an iPhone X placed on it. Please note that this is an imported product, so there may be minor stains or scratches. ⚠️ If the outer box is damaged, it will be repaired with cellophane tape before delivery.
