◾️Product Name◾️ Smartphone Bluetooth Remote Control "TUNAI BUTTON" ・Body Size: 3.5cm square, 0.8cm thick ・Accessories: Rubber band x 3 Rubber attachment Docking Battery pin ・Main Functions: Music playback, phone calls, selfie shutter ・Battery: Button cell (CR2032) ・Purchase Price: Approximately 4,000 yen ◾️Overview◾️ I purchased this on Amazon and used it with love because I wanted to play music and YouTube from my smartphone while driving. The rubber band design allows it to be attached regardless of the handlebar diameter, so I was able to install it at the base of the handlebar as shown in the second image! My friend's car had a remote control embedded in this location from the start, so I got closer to my aspiration ^_^ It was comfortable to operate my iPhone easily while driving ♪ I initially installed it on the handlebar, but it became a hindrance to driving, so attaching it to the base was the perfect solution! I haven't used it since the battery died, and it's a waste, so I'd like to sell it to someone who needs it ^_^ I have lost the instruction manual, but it is available online, so please refer to it.
