These are circle molds: ◯ 9cm x 3cm… 3 pieces ◯ 8.5cm x 2.5cm… 3 pieces I mainly used these for flatbread baking, placing a baking sheet on top. I cleaned off as much of the dirt as possible after baking, but there are still some remaining spots. The smaller ones can be stored inside the larger ones, making storage easy (see the last photo). Thank you for looking. #EnglishMuffins #HomemadeBread #Flatbread
