This duster comes with a gentle chenille microfiber sleeve made of an 80% polyester / 20% polyamide microfiber blend with a 1,500 GSM weight. This material traps and removes dust and dirt without damaging surfaces, providing a streak-free clean. This sleeve features a secure hook and loop closure to affix to your duster wand. It easily slides on and off, and its removable, machine-washable design makes it easy to reuse, replace, and keep clean over time.
