I've been gradually lowering the price, but this is the final price. It's first-come, first-served. By the way, although it's not in the photos, I have the case, so I'll include it. This item was used with a Chair One. I'm selling it because I've been using a low style with a Grand Chair more often. I've only used it twice: once for a day camp and once for watching a fireworks display. I will not be lowering the price at all, so please refrain from comments or negotiations asking for a price reduction. Note: This item will be shipped via Takkyubin Compact. [Product Description] This is a collaboration product with Vibram. By attaching it to the rubber tips of the chair, it prevents sinking in sandy areas. Also, when used indoors, it won't scratch the floor and provides grip. Helinox Vibram Ball Feet Black for Chair One, Chair Mini, Chair L, Tactical Chair, Chair Two, Cot Leg, Speed Stool
