Mary Berry With Lakeland 23cm Square Cake Tin 4 "Superb Cake Tins" Mr Jean Thierry 24 November 2016 I bought two of these tins three years ago and they have performed faultlessly every time I have used them. When I originally purchased these tins, there was a 23cm square cake tin liner to match, which I also bought. Sadly, the liners have been discontinued, which is a great pity. I will now have to resort to using the 23cm Baking Parchment Liners for the base of the tin. Despite this slight inconvenience, a superb product.
