What did Kyouko get Ren for his birthday?

With how Kyouko's bizzare mind works, I think it's nearly impossible for me to imagine what she gave Ren. Too many possibilities... and that's why I like her. lol

She gave Him a glass with 장미 going around it filled with gelee au vin

I think that it wasn't really shown in the manga. All I saw is the weird shaped box but never the gift. 또는 I probably missed it.

They haven't said it yet. I re-read the chapters from valentines 일 to the latest (innumerable times) and they haven't mentioned it. Though it was shown twice 또는 trice that Kyoko was extremely embarrassed about it..................I thought and thought and I have no idea..........

i have been thinking about this a lot of times i think it has some thing about the stone that 옥수수 give it to kyoko i haven't seen it for a long time ?
