Dice as a decision, buying American, buying precision and why it matters

My players already know that these are my dice of choice (and Santa, these would be a great present for a DM who has been extra nice.) and the reason why can be best understood here.

But did you know they are made in America?
Did you know you can get them made of recycled materials?
Did you know they are AWESOME?

And I'm not just a speaker for these dice are teh awesome movement...I'm also a member. In addition to the sets I've bought for most of my players, these are my own dice. My DMing ones (on the left) and my LG dice (used only when I play LG characters.)
