5 Tier Round Multilayer Wedding Birthday Anniversary Baking Cake Tins Pans - 6 7 8 9 10 - EUROTINS

what is the material made it

How deep are they?

Does this require lower temp and long time to bake than normal? all the lower reviews seems to have same issue w hard time baking a solid good cake??

if this pans are not dishwasher safe how do you clean them?
