How do you display your carton/sealed figures?

[Plex7]

I have quite a few X-Men '97 figures that I don't really want to open up. A few from the 90's as well. I've been keeping them inside my 2nd IKEA glass cabinet while I save up for more 1/6 scale figures. That time has come, and I have no idea how to display these. Need ideas. I have an open wall where I can hang them but no clue how. Nailing the wall not an option, tape using a reliable method is fine.

Back in the day, I used push pins to hang my carded McFarlane figures on the wall. I created a frieze of them in my entrance hallway. They needed to be dusted once a month
