Joy-Con Holder for iPhone

Need an additional ring-shaped magnet. Its outer diameter is 54mm, the inner diameter is 46mm, and the thickness is between 2.5 and 3.5mm.My own mobile phone is an iPhone 14 Pro. For other models, you can refer to this dimensions(150*74mm). If there is no magnet on the back of your mobile phone, you can try installing a mobile phone case with a magnet.Tips: If it's initially tough to get the thread started, try turning it back and forth slightly while gradually screwing it deeper.
