Can you imagine my surprise when I came into a store known for its creativity and unique stuff (cards, mugs, lamps, photo frames, etc) called FLO (I guess it's Polish store, but maybe you know it) and saw THIS:
[the mascot on the right is the original one I brought from Japan with me]
I was surprised because all of their stuff I saw so far has its own design, very characteristic, and now they obviously took Ai's Love character and made it into keychain. I'm 100% sure they just found the photo in the net and didn't even realise it's some artist's trademark.
Here you can see some of their stuff:

So, if there are some Polish Ai-chan fans, just visit FLO and get it, it chep, 3,90zł (about 1 euro)
