I am SO glad you like the blocks!
Full disclosure though: I
wanted to have them made in the US and tried very hard for it to happen. Sent out 12 RFQ's to US manufacturers and only 2 even responded. They needed minimum 100K piece order and the quoted price was double what I currently sell the blocks for. Seriously, the quoted price was $400-$500 for a set.
Sad commentary, but it is the reality we live in
With that said, the raw materials are from the US, the molding and assembly takes place offshore, sales and distribution take place in the US.
So over 80% of the money changing hands stays in the US.
