AirBuggy Accessories: This is a drink holder. The exterior is made of nylon, and the interior material is like a cooler bag. It's sized to fit a 500ml plastic bottle perfectly. Please check the photos. - Brand: AirBuggy - Color: Black - Material: Nylon - Function: Storage bag Used about 10 times. I think it's in relatively good condition, but the string looks a little fuzzy. Please check the images. Thank you for looking. Price is not negotiable. No pets. No smoking.
