The Deluxe SetThese reusable, eco friendly lint rollers pick up dog hair , cat hair , lint, crumbs, and dirt lightning fast, saving you hundreds of dollars every year on disposable rollers. How does it work? The special silicone material is super sticky when dry, but slippery when wet. This allows you to rinse the Sticky Buddies clean under hot water, then go right back to cleaning. Use the regular size, Sticky Buddy, for everyday use on your clothes and furniture.
