Product review (5 stars): Great "Fat Trapper" liners
These are the necessary liners for the "Fat Trapper."  Their foil lining and fold-tab closure make them spill-proof and very easy to use.  (The "Fat Trapper" is a rectangular plastic box with a lid that can be left on the counter by the stove. It's a great kitchen addition for anyone who cooks foods that leave behind cooking grease, especially for homes with septic systems.
