I bought these tart pans to make smaller tarts. I usually make 9-1/2 inch tarts with a pan that is 9-1/2 inch diameter. These tart pans are nonstick so you can easily lift off tart from pan without breaking tart. They have removable bottom so you can push the bottom up and easily remove the tart. Having a smaller size enables me to make smaller tarts for sale rather than selling one big one.
