I have several cakes I have been making for people recently that I am just unable to locate cake boxes for. The largest box I can locate to buy is a 12x12x5, minus $28 wedding cake boxes. Most of my fondant birthday theme cakes are all 8 inches tall. Is there anywhere you can buy 12x12x10 in boxes?
Scroll down to 12 x 12 x 10.
Uline has corrugated boxes in whatever size you want, but you have to order 25 of the same size. So if you have a size that would work for most of your cakes, they have pretty good prices. They have 12 x 12 x 10 right now on sale .... 69 cents each x 25 boxes plus shipping.
Hope that helps !
