For $7.50 you can get a dummy phone which looks a lot more realistic. A quick search on Aliexpress shows this for the iPhone X, and there are plenty of other options. (I had a bunch of the iPhone 8 models for a work project. The only downside is the glass is most definitely NOT Gorilla Glass).
Back when I lived in Japan, stores had plastic dummy phones to show you what they looked like and let you pick them up. I guess that went away when the “Galapagos style” phones died off.
