This is my business card holder, which has some kind of mountain motif (at least that's how the pattern looks) which is why I call it Mountain Hill.
The removable or glue-in element allows different color variations to be created, even without AMS.
Please note, before inserting the front, lightly file the side parts with a fine rasp so that it fits better.
I also designed a second version for easy clipping in case this is a better option for you.
Have fun with it!
