diablo-proHeard of adults collecting sports cards, bottle caps, and comic books? It's about appreciating few of a kind costum made things in life. A lot of us just don't.
These are custom made tops that are usually made in small batches. They are used in games or just a desktop stress relievers. Or to sit in your man cave as a shelf queen. If you do a search you will find your answer even better than my examples.
It's just appreciating things that are made oddly better than everyday items you don't normally see. But at a cost.
