Clean Room Sticky Mats 36" x 45" (4 Pads, 30 Sheets per Pad) - Blue | Dust & Contamination Control for Laboratories, Hospitals & Electronics Manufacturing | Anti-Static Floor Mats for Cleanrooms & Sensitive Environments

I use these at the door to my house from my workshop. Collects the metal shavings and other small items from getting inside the house. A little tricky getting the correct tab pulled up to peel off a used sheet. In my case, each sheet lasts about a week, so this purchase is good for about 4 months use.
