Shikgekikkusu is my absolute favorite type of Japanese candy! I absolutely love it, it's probably the most sour thing ever created, and I mean sour! it's like eating a Harribo Gummi Bear and eating a whole pack of Sour Skittles at one time, the strength of the "sourness" is shown in the top right corner of the pack, and ranges from 600 to 900.
I don't know why I love them so much, but they're delicious, and I highly recomend them!!! my favorite flavors are Soda (blue pack), and Rainbow Fruit (not shown above).

(it's in Japanese) if you can't read Japanese, I suggest going to www.Asianfoodgrocer.com
