With 'heat-spread' properties (made from anodised aluminium which distributes heat faster and more evenly) and a naturally easy release surface - ensure a good rise for a lighter sponge and easy glide out. Simply fill and roll for a classic teatime treat. Lightly greasing the anodised body will help to guarantee that your bakes will slide out with ease. Cups are 8cm width. Handcrafted in Birmingham, England. Exceptionally strong, professional grade materials. Heat spread technology - the special alloy core used in Silverwood's bakeware spreads heat fast and evenly, producing perfect baking in a reduced time.
