Product review (5 stars): Stovetop Gap Guard
Countertop is tile and it was roughly cut -- these hide the gap very well and really improve the look of the countertop. I'm thinking of using one between the washer and dryer to make more room in the laundry.
My stove top is black, so I got the black ones since the countertop is off-white -- I'm very pleased.
They trimmed in length quite easily with a hack saw -- no power tools were unpacked yet.
