Box Extension
Height extension for cake box, PME Cake
The PME Cake Box Extension is a collar that attaches to the rim of a square or round cake box to increase its usable height. It is not a box in its own right, but an add-on for an existing box.
It lets you transport a taller-than-usual cake (tiered cake, bulky decoration, topper) without changing boxes or improvising a makeshift solution.

Your questions, our advice
Does this extension replace a cake box?
No, it attaches to an existing box to increase its height: it cannot be used on its own and requires a compatible base box.
Is it suitable for all cake boxes in the catalog?
It is designed for standard square and round sizes in the PME Cake range: check that your box dimensions match before ordering.
Is there an alternative for a set of several extensions?
Yes, the Box Extension set/3 offers the same accessory in a pack of three, useful for fitting several boxes or keeping spares in stock.
