Clicks is a physical keyboard case for iPhone. It's not the first, but it's nicely-designed and something about is, well, clicking.

It's $140 for iPhone 14/15 Pro (or $160 for a Pro Max model) and comes in yellow ("BumbleBee") or gray ("London Sky"). It connects via USB-C (but not Bluetooth, because Bluetooth is bad) and represents an amusing affront to everything the iPhone's creators have tried to achieve.
