(1 customer review)


In Stock

It is specially sized to fit into white cake boxes. Packed in sets of 4, each card sits neatly into the corner of the box to extend the height of your white cake.

Product Details

Cake Box Extension corners 10 Inch - Pack of 4, extends the height of the cake box to fit taller cakes. They are plain white colour which makes them suitable to use with our plain white cake boxes.

In addition, we also stock cake box extensions in different sizes. With this product, you will make extra space for those larger celebration cakes - especially tall tiered wedding cakes, anniversary cakes, or birthday events!

This style of cake box extension corner is also, much more sturdier than the hinge style of cake box. It gives approximately 14'' in height for transporting your cakes and treats. This plain white cake box extension is suitable for single tiered cakes.

Ideal for lifting the lid on your box to accommodate taller cakes and decorations by protecting all sides!

The cake box super extender simply slides inside your usual cake box to increase its depth, then the lid of the cake box fits on top of the extender.

Super Extenders are perfect if you have tiered wedding cakes or celebration cakes that would not usually fit into your usual sized box.

Please note, this item is not a cake box. It's specially designed to fit inside a regular cake box to make it taller.
