This lint roller set by WOWGO has a larger roller, and a pocket size travel roller. The rollers are made of a sticky material that is endlessly reusable. Gone are the days of peeling sheets of disposable lint catchers. With these rollers, you either take the cover off or open it up and start rolling. When the sticky surface is covered with a material you simply take it to the sink and wash it with a little soap and water then rinse it off, and it's ready to go again. I personally have a dog that sheds a lot of hair all over the place. I can take the large roller, and simply roll it over her body and get a lot of loose hair off of her that will not end up on our clothes or carpet. I love the travel roller because I always find loose lint or dog hairs on my clothes when I'm out. I keep the travel roller in my purse. Its dimensions are 2.51"x 2.16". The larger lint roller is 3.85"x 4.52". The only thing I want to warn those with long hair about is to be careful about getting your hair close to the rollers because your hair will stick very easily to them. Overall I love them because I'm tired of pulling sheet after sheet of paper off to get a sticky lint removal surface.
