what 😐

i lost 50 karma for a thing that gives you 10 karma...

Thats weird...

um since when did this exist?

These things aren't just used to get 10 karma in return. You can use/anoint them on a spray paint dispenser for a chance to get rare spray paints out of them (if you have a dispenser that is). Putting them in a mysterious bag can give you a bunch of spray paints in return when shaking the bag. You could also sell them on the market, I have two of them for 70 buttons each.*

*edit: i noticed you did end up selling one for 70. All you gotta do now is wait for someone to buy yours. It's how I ended up making most of my buttons after all :]
