Thank you for viewing. This is a set of two umbrella covers and one waterproof storage case. The "Biyooon-do" umbrella cover is a smart long umbrella cover that is useful for commuting to work or school on crowded trains and buses on rainy days. Simply put it on a wet umbrella to completely guard against water droplets! It keeps both you and those around you dry. It's a compact size that's convenient to carry, and comes with a silicone strap that can be attached to your bag. After use, if you put it in the included waterproof storage case, you don't have to worry about getting your bag wet. Made of plastic, it's easy to clean, just wash it with water and dry it!
