I'm sure most of you have seen those Bikkuriman wafer cookies [or their highly coveted sticker "seals"] at some time in your lives. They're in like every toy shop // convenience store in Tokyo and I always eat a shit-ton of them when I'm there to get the stupid stickers, but for some reason they seem to be almost nonexistent in the United States. I was curious if anyone has seen any around their city or if anyone knows where one can obtain them.
