an alternative to our best-selling cake box corner extension cards
these solid single-piece height extender cards create a completely enclosed cakebox
great quality - much better than the super extender and cheap non-branded versions
trade pack of 25 also available - save nearly 30% on RRP !
extends the height of the cake box to 35cm / 350mm / just under 14"
taller 16" high Windsor box extensions also available
perfect for stacked, extra tall or tiered cakes
a simply idea that works perfectly - and the combination of cake box and extension is still a lot less expensive than the specialist stacked cake boxes
re-usable - just remember to ask your customer for it back (!)
this item is made to fit a 10" cake box
the 10" cake box (see pics 2 and 3) is not included
PLEASE NOTE this is an outsized product - approx 50cm x 35cm when flat - so we can only ship by courier to UK and European addresses - it is too large for Air Mail and too vulnerable to send by Royal Mail
supplies flat and creased for easy folding into shape - no glueing required
not retail packed
made from the same hygienic card as the cake boxes
