I'd have to look myself, I'm not super well aware of Karatbars.
I personally like AnthemVault. They have integrity. Anthem Blanchard's father was James U Blanchard III who freed up gold to the American people in the early 1970s after decades of a physical ownership ban initially implemented by FDR in 1933.
He's also starting a gold-backed cryptocurrency called AnthemGold :P
Thanks for the recommendation... Ah 1933 with proclamation 2040, been under temporary military ever since.
