Domino Premium Pure Cane Sugar Cubes Dots, 1 Pound Box

Is this a 1/2 teaspoon or 1 teaspoon per cube? I am looking for 1/2 teaspoon.

Is this the same box that is on Walmart for $1.70?

How many cubes per box?

If i order from this listing, would i get cubes from the yonkers, ny refinery as in the picture? i want vegan ones that dont use bone char.
