At year's end and on New Year's, Japan and many Asian countries often sell lucky packs, fukubukuro. These are bags of random or unique items that you buy at an exceptional discount. The caveat being that the contents are a surprise. But for me, surprises are Super Prizes.
The Grab Bag I got from Sanrio is just like a Lucky pack. I also recently got a Lucky Pack from MaruQ , with Sweet Loulita's help. ( I hope to blog about it soon; I must purchase online storage for my photographs. Flickr Pro, here we go.)
