Toss-It! Bag - Fill and Toss Away Unwanted Kitchen Grease by Toss-It!

Can you use the bag more than once until it is full?

Do the bags zip closed until filled? Keep the kitchen or frig from smelling or attracting bugs?

Can you pour the oil while it still hot, or do you have to wait for it to cool down?

Does the bag roll down/folder over? I have a 5x5 porcelain grease container and I want to use the bag as a liner.
