This is one of several I purchased to attach to my bicycle. I am selling it with the recipient paying for shipping. Since it exceeds 4cm in thickness, shipping costs will be a bit high, so I can hand it over to someone along my commute route in Tokyo. This product is for 4-6 inch phones, and I didn't use it because it didn't fit my smartphone with a large screen. Shipping via non-standard registered mail is also possible. Please consult with me beforehand. It has not been attached to a vehicle. This is a 360° rotatable silicone smartphone holder, perfect for bicycles and motorcycles. - Type: Smartphone holder - 360° rotation function: Yes - Material: Silicone - Application: Bicycle, motorcycle, stroller - Color: Black High-quality silicone material: This holder is made of high-quality medical-grade silicone material, which has good elasticity, stretchability, corrosion resistance, and water repellency. The hooks on the top and bottom of the smartphone holder can securely hold the four corners of the smartphone. The silicone absorbs shocks while driving, so there is no need to worry about it falling due to vibration or impact. Because it is flexible silicone, it will not scratch your smartphone. The silicone holder can be kept clean at any time by washing it thoroughly with water when it gets dirty. Thank you for looking.
