This item was designed based on “Box with a tree” (RF-14).
Like the “Box with a tree”, the direction of the item when moving the device is the key to unlock itself. The “Box with a tree” has two devices, and it requires us some skills to solve.
On the other hand, this item has only one device.
Then it is easier to enjoy the wonder of this device.
The source of the image of the pattern on the top is drops dripping from a leaf. (Yosegi: Junno Kobayashi)
