If it's so standard, then it should be selling everywhere, where ?

If it's so standard, then it shouldn't be a problem for you to name a few places where can we buy this particular chess board

Seem like a library size Meghdoot set to me.

This board appears to look the same as in the video. However this one is maybe smaller than what was videoed. Looks like an Amazon or eBay common board.

Here looks like a bigger version maybe. The art work is different and the wood is different but seem like it might be what you are wondering.

WholesaleChess sold a 20 inch version of that board but with different pieces. I think it is the same as in the video. Unfortunately, they do not sell it anymore.

Thank you very much for your time! Now I see why no one can find it, they just stoped selling it, that's why.
