Box Extensions
Cake box extensions
Extensions and tall boxes with windows to increase the available height and accommodate a decoration or an additional tier without changing the box.
What is a box extension used for
An extension is added to an existing box to increase its height, without having to purchase a larger model. It is suitable for a cake whose decoration exceeds the standard height, such as a tall topper or a two-tier cake.
Tall boxes with windows
Tall boxes with windows are available in several sizes (from 20x20x25 cm to 40x40x30 cm) and let you see the cake during transport, while providing enough height for a tiered cake or a large decoration.
Frequently asked questions
When should you use an extension rather than a tall box directly?
An extension is suitable when the base box already exists in the correct length and width, and only additional height is needed.
Do the extensions fit all boxes?
They are designed for a specific base format (the same length and width): check the dimensions for compatibility before purchasing.
What size tall box is suitable for a two-tier cake?
It depends on the combined diameter of the tiers and the height of the fully assembled cake, including the decorations; a few centimeters of clearance above the top is still necessary.
