This is magnetic smartphone holder for motorcycles. Unlike the type that attaches to a general handle, it is attached to the tank using a magnet. Therefore, you can keep the area around the handlebars clean and secure your smartphone without compromising the look of your bike. The width of the clamp part is approximately 5 cm in the most closed state and approximately 10 cm in the maximum open state. [Note] Most smartphones of standard size are acceptable, but please take into account the thickness of the smartphone cover being used and be sure to check the dimensions before purchasing. Also, since it is attached with a magnet, it can only be used on iron tanks, so please check. Also, the magnet part is coated with rubber, but please be careful when installing it as it may scratch the tank if you place it too forcefully.
