Cake Box 12x12 

The 12x12x6 box is suitable for a 10" cake on a 12" board with top decorations.

Both the 12x12x10 and the 12x12x12 boxes are taller boxes to hold your tiered cakes.

The newest tall boxes are what they are calling a Flex Box. We received a 12x12x12 with separate lid.  It has built in bends into the upper sides where you can bend and detach that section and it converts to a 12x12x10 or take out 2 sections and it becomes a 12x12x8 box with separate lid.
