If you’re a parent with school aged kids then I’m going to assume you know what these are…stretchy little book covers. I honestly couldn’t begin to tell you how many of these I’ve had for my son’s school books. Although they are only like $1.00 or less at Walmart I never bothered to throw them away. I just ended up tossing them in a drawer. One day I decided to use them to dust the furniture and to my surprise they did an awesome job! They’re perfect because they even polish without the use of any cleaners. I also use these on my hand painted signs. After I wax my signs I use them to buff the wax and they work perfectly because them don’t leave any lint behind.
