Space saving: The holder is equipped with two storage cups by adjusting the rotating base, small in size and large in capacity, aiming to save space in the car, and can hold two drinks in same time. Extender Cup Mouth: The adapter is most suitable for bottles/cups with a diameter of 3.0 to 5.9, and fits most bottles of size water. The cup body can be automatically raised or closed when the cup holder is not in use to keep the car clean. Shockproof cup base: If there is a gap between the cup holder and the bracket base, use the buffer sponge pads to fill it, which can not only reduce vibration but also stabilize the bracket. The bottom of the cup is made of non-slip foam. Wide Application: This 2 IN 1 car cup holder will save you countless times from digging between the seat and the center console to find your cell phone, your credit cards, cash, keys, coins, pens, wallet, etc.
