Easy No-Mess Pie Crust Maker Bag, Rolls 14-Inch Crust For 11 to 12-Inch Pies, Set of 2

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?
