These work so great. They are dusters with 180’ turn. You can dust in tight spaces I like your window shades. Books shelves that are hard to reach you can use the wand. It reaches 6 ft. It locks in dirt dust hair and allergens. You can use on multi surfaces. I use them on every thing. They are safe for all surfaces. I have a dog so it’s good for getting those pesky hairs from him. I do behind the tv with the wand. And it clings to the duster. Then I just pop it off the wand and through away. So easy.
