Cylinder box hinge?

Hi community. I am trying to research or understand how a cylinder box (make up for ex.) is designed in order to not show the hing from the outside. Is there any good source where I can research how to make an opening lid with an “invisible” hinge from the outside. I am curious about this and unfortunately I do not have any element with me that exemplifies this.

Thanks a lot .

Hi Siemen. I was wondering the ones in makeup. I think I find a nice pic. Its more like an integrated hinge. Solved it . Really appreciate your concern and information :slight_smile:
