They're obviously a slight variation of the Merida set. One minor variation I see is that the points on the black queen are black on the Merida but white on the set you posted.
Here are couple places with downloads. The downloads appear identical.

Can anyone identify this piece set? It's used in a lot of the older video lessons, and I'm wondering why it's no longer an option in live chess or anywhere else on chess.com. Anybody know if it can be downloaded somewhere?
