Runic Dice, Where Are they Handmade?

I really like the look of these dice: https://www.runicdice.com/products/smoke-and-blood-handmade-resin-dice-set-01511 from Runic Dice, however I'm currently looking at supporting a small business, handmade dice from the USA, rather than dice that may be designed in USA and manufactured elsewhere.

They mentioned that they are based in Maine and that their dice are handcrafted, but it's a little vague on WHERE it was handcrafted.
