This is a 2U Right-Stepped Slash & IntlRo Keycap for JIS Layout.

Only left side of the key switch activates even if you press the right side of the keycap.

This keycap uses OEM profile.

You will definetly not need this keycap unless for specific problem-solving.

I made this keycap because key rollovering with IntlRo didn't work well with my keyboard, especially when over 6 keys are already pressed. 

.blend Blender project file included. It's messed up but might be useful for customizations.
