This is a "Kasa-Ashi" (umbrella legs) purchased through the crowdfunding platform Makuake. By attaching these legs to your umbrella, it can stand on its own. It's convenient and eye-catching, so you won't have trouble finding your umbrella. This is a set of 4. Individual sales are not possible. The box is slightly damaged, but the item is new. For shipping, I will likely take the items out of the box, but I will include the box as well.
