I was looking through the shiai thread and read something about march madness items that got turned into tc. What were the March madness items?

I've joined on March Madness Event, and the Items were Headphones, Green Hat, Red Submarine and Shutter Shades, Shutter Shades won, and I sold them long ago.
Here's the Thread

Why do the items still exist. From what I read they were supposed to be turned into tc

I know people who has them, but I don't know about that the Items turned into TC, no comment.

It ended on the April, what would you expect from an event that ended on the April 1st? Manyjokes

Ok thanks
