Using MP6 icons for plugins

I came accross this image:

In the picture, the shop icon is in the same flat style, as all the other Dashicons. Since I like my web interface clean, I would like my plugins to use the MP6 icons too.

I do know about the GitHub-site with the Dashicons:
http://melchoyce.github.io/dashicons/

My question is:
How do I make my plugins admin-page have a Dashicon, instead of the current ‘Gear’ icon?
