Each metal plate is lightweight and slim, so it won't add bulk to your device.

Usage Scenario

Mike drives for a food delivery service and switches between his personal phone and a work phone throughout the day. His magnetic car mount only works with phones that have built-in magnets, so he was stuck using a bulky clip holder. After sticking one of these metal plates inside each phone case, both phones snap onto the mount instantly. He no longer fumbles with clips or straps, and the slim plates do not interfere with his cases or charging.

Micro Comparison

Unlike adhesive magnetic rings or bulky magnet stickers, these metal plates are thinner and more discreet. They do not add noticeable thickness to your phone, and the set includes multiple sizes so you can match the plate to your specific device and holder. Many universal magnetic plates only come in one size, but this kit gives you the flexibility to choose the right diameter for your setup.
