Jenga Extreme is a great gift for your Korean friends or colleagues.
It costs around 40,000 won here if you can find it, and $29+tax in Canada (superstore and walmart) last time I was there. It's basically like Jenga, except you can build the tower at different angles.
I also have several Scrabble games--wooden tile edition, still in shrink-wrap. I've only ever seen the plastic ones in the stores here.
My wife wants me to get them out of the house, so I'm offering these games for 20,000 plus shipping (4,000won). I could probably sell them for a lot more on auction, but my wife is too busy. You can combine the shipping if you want multiples. I think the shipping will be the same for 2 or 3.
