Are they used for anything, if so where and what? Please help, coz I have like fifty that I don't know what to do with. Ping me!

They were used to buy items from an event shop during the Vesnali/Easter celebration some time in the spring. They can't be used now, but I'm sure they'll be useable again come spring.

They used to be 'Easter Tickets' -- last I checked, you could still use them here:
