This work kit was developed for our third annual "Karakuri Puzzle in Hakone"in 2013. "Inu Kuwae" was an extremely popular souvenir from Hakone, so we decided todesign it into a workable kit. In the original souvenir, a cigarette rolls out and is caught in the dogs mouth when the drawer is pulled out. However, in this work a toothpick appears, not a cigarette. An interview with the designing craftsman is also included.
