Extra Strong 30cm Silver Cake Board - Round 3 "A bit of a non event." 05 January 2018 It is a nice enough cake board - but extra strong? It didn’t seem very different from the others and I would have liked it more if the silver coating had been more durable. That said, it held the cake well enough.
