I got this at a great sale price so bought a few rolls.  Very useful for RV cabinets, inserts to jewelry cabinets, tool chests, ... everything!  Lays flat, grips the bottom, and prevents sliding of anything on top.  Easy to cut straight, since you can follow the grid lines.  No curl up on sides, does not degrade easily with use, and washable.  Cheap too!  Buy some, and you will find some use for it.
