No studs are missing. This design is perfect for the coming season. You can store cards as well as your smartphone, so you can go out with just this one (^^) I use an iPhone 14 Plus (16cm tall, 7.7cm wide, 8mm thick), and I was able to store it without a case. For your reference... Size: 10cm tall, 17.5cm wide, 2.5cm depth There are many adjustment holes, so the length can be adjusted.
