Cake cards at 2 mm thick are ideal for multi tiered stacked cakes where the boards need to be hidden from view, using the same size board as your cake they are for gateaux, sponges, and light weight cakes. Available with hygienic silver foil covering in round and square, sizes from 3" to 12".
Polycoated cards are the thinnest at 1.5 mm and have a non stick coating so will not allow the moisture from your cake to leach through.
