Fukubukuro (福袋 ?, [ɸu͍ku͍bu͍ku͍ɽo], "lucky bag", "mystery bag") is a Japanese New Year custom in which merchants make grab bags filled with unknown random contents and sell them for a substantial discount, usually 50% or more off the list price of the items contained within.

One of the best presents I've ever gotten, you can tell my secret santa really cared because he even included a little Kendo lego figure haha.

If you are reading this Secret Santa thank you so much! And thank you for your service!
