So I got this case for my iPhone 15 Pro since it allowed it to lay flat. However the Volume and Notification buttons have no texture to them, making it difficult to tell which button is which when it’s in a pocket.

So I had an idea. What if I heated a file with a heat gun. Then pressed it into the Notification button.

This was the result and I am very impressed. No way I will mistaken it with the volume rocker going forward.
