Unused REALFORCE R4 Keycaps Japanese Layout Blue-White Oak

This is a color keycap set compatible with Topre Realforce R4.
The color is Aoshirotsurubami (青白橡).
Japanese layout, no kana legends.
No missing parts.
Purchased new from the official shop, but it didn't quite match my image, so I am listing it in unused condition.
The item in the middle of the photo is not included originally, so it is not a missing part. *As shown in the instruction manual photo.

Returns and exchanges are not accepted.
Please purchase only if you understand and are satisfied.
