I received this from my mother-in-law, but I have a lot of them, so I'm selling it. POINT 1: Holder for two drinks. When opened, the holder can accommodate two drinks. It's also possible to use it for children or to separate hot and cold drinks. POINT 2: Safe design with non-slip feature. Silicone non-slip pads are attached inside the holder, preventing bottles from popping out even on bumpy roads. POINT 3: Easy installation. Simply loosen the knob and clip it on, making it easy to install. It can be securely fixed in place without being limited by location. POINT 4: 360° angle adjustment. The rotatable design allows for angle adjustment, enabling installation at various angles.
