Zenker Glass Fibre Silicone Rectangular Baking Pan 5 "Excellent!" Mrs Ramsay 02 September 2019 I've used this baking pan twice now and it has produced two beautiful banana cakes with no messy tin to clean. The cakes tipped out without any problems. I would advise placing the pan on a baking sheet rather than straight onto the oven shelf. Well made and looks to be long lasting, I will be purchasing more to complete the set.
