Set of two black drink holders compatible with plastic bottles. Convenient when the drink holder is located low and difficult to use. I previously purchased these at Costco and used them only once, but they didn't fit my car well. You can secure them to your car's holder by turning the central adjustment dial. They can accommodate larger bottles and water bottles that don't fit in regular cup holders. Please note: A 500ml plastic bottle will stick out a bit, but there's a rubber grip to keep it stable. - Color: Black - Shape: Cylindrical - Application: Drink holder - Size: Compatible with plastic bottles - Quantity: Set of 2 - Material: Plastic Thank you for looking.
