League of Legends Key Chains?

Not sure if this is the correct board or not, but I figured it would get the most attention here.

At one point, maybe a year back or so, I saw someone post on boards with a key ring full of League of Legends key chains. They were all the different weapons of the League champions at the time. I went looking for the post, but searching anything with "key" in the word brings up discussions on hextech loot keys. I was wondering if anyone knew where to get a set, or if there even is a full set sitting around. I've seen some on Amazon and different fan-site stores, but they're all sets of 25 or individual, not an entire set. Is this the only way to get them, or does anyone know of a place that sells a full set, or at least has a full set as individual pieces?
