Nice but needed modification
Size: 21 1/2 in. W x 1/2 in. D Style: Universal Pattern Name: Side Splash
Contrary to the picture on Amazon the sidesplash is not 90 degrees on each end. In order for it to work on my vanity top I had to use a diamond bladed saw to make 1 end 90 degrees. Looks nice and the white is bright and not dingy as the picture shows on Amazon.
