This xiangqi set popped up on eBay. First picture in the listing showed a very nice wooden box, which opens up and serves as the board.
The buy-it-now price wasn't exactly low, but what interested me was the mention of 'metallic' pieces.
I asked the seller whether that meant the pieces just looked 'metallic' (due to the paint used or something similar) or whether they were actually made of metal. Very helpfully, the seller posted a short video clip in which he (very carefully!) hit one piece against another. Sound was unmistakable: these were actually made of metal!
Very nice board indeed ...
... and very nice metal (!) pieces, quite heavy as well.
Despite the highish price, very happy to add this set to the collection!
