I am sure most people are familiar with how every ethnic/immigrant family uses Danish butter cookie tins to store sewing supplies.
There is a large and enthusiastic community of people who are really into keycaps for their mechanical keyboards. Evidently there are enough of them who like the aesthetic of the butter cookie tins that a themed keycap set was born. The world remains an incredible place.
If you want to look at the many designs available of such things, Etsy has a lot of vintage cookie tins to browse.
