4 on/off switch modules, one cover plate, two base plates, one wall box.
300yen for all
The base plates and switches are fine.
The cover plate is dated, but fine.
If you live in a very old house with even older fixtures (black switches that look more like those in the USA), you will see that these are the next level up!
You can buy all these pieces separately at any DIY home center. Check out the prices and get back to me if you wish.
Can be mailed with advance payment for items plus the shipping (probably for about 200 yen, anywhere in Japan)
