Mrs. Anderson's Baking Easy No-Mess Pie Crust Maker Bag, 14-Inches, Clear

Is it easy to clean?

I'm looking for the 8-9 inch pie crust bags but it says "11 inch" on the package. What is the true size? Thank you

which do is better larger or smaller size..which is most preferred for a 10" pie crust?

Can it also be used to roll out pizza dough?
