"This has been my work I've been doing for this summer: A Passport!
Currently, while available on the Workshop (https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1815296105), it's currently in Iteration One. Next time it's updated, this model will be in Iteration Two, and you'll be able to use these skins in place of Normal, Normal with Approved, and Normal with Denied.
Included in the Workshop item is a Stamp model. So that you can stamp people with approval or denial."
