Yeah, those are for the Air Pro, the larger set. I do not have that, I have the Air and the Evo (which use the same, smaller piece size).
Would love to get a set to fit those boards.
Can you post the links he sent or message me with them?
I will also reach out to him.

I saw a blog post about Indiachessart on Etsy who makes fantastic wooden chess pieces. Supposedly he'll drill the holes ahead of time. They run around $125-150 or so.
**Actually, I just heard back from him and he confirmed that he does sell sets that are pre-drilled for Chessnut Air. He has a website indiachessart.com
Do not see the pre-drilled Air (the smaller ones, correct?) on the site.
Does he make them as needed or am I just missing them?
Having looked at his site, I didn't see any listed as pre-drilled either. He sent a bunch of links and said they would work with the Air, but I'm still trying to get clarification whether or not they are pre-drilled. I don't think he speaks much English.
This blog post is where I first learned about them. https://www.chess.com/blog/vitualis/chessnut-pro-best-and-easiest-way-to-make-custom-chess-pieces Maybe he could answer?
