Sof'Feet 12 pak Replacement Abrasive Screens 12

I need 100 grit replacement screens that are 1 1/2" wide by 4" long. What are the dimensions of your product? Thanks.

The original screen on my callus reducer measures approximately 3 x 1.5 inches, but the specs here indicate 3 x 1 x 2. Are these specs correct?
