This work was designed for Karakuri Puzzle Party in Hakone 2019.
An improved version of the 2018 Christmas Gift “Bars Box II” (KW-37).
In the previous work, two of the twelve bars were unable to move because of the mechanism.
This work has been redesigned so that all bars are related to the device.
There is also a fake route.
And the details of the internal structure have also changed.
