5000jpy price is per box regardless of size.
There are two sizes available. I think 8 are the same size and one is shorter. They all have the same footprint.
65cm x 40cm by 25.5cm height (the shorter single, not guaranteed to be accurate, we did this in a big hurry)
mostly excellent condition
there might be some dust / a fingerprint on the outside
Sold as is.
Common crafts:
covering the Chabako with Japanese paper (washi)
covering the Chabako with cloth making it into a seat / piece of furniture / room decoration
Here is a link to a company that makes the boxes into furniture and sells them.

But there are people who learn to do it on their own very nicely!
