Our cup holder and organizer has a stretch and shrink feature, which can accommodate the stacking of larger objects and can be rotated 360 degrees, whereas the lower part has a relatively stable structure.
The cup holder is suitable for most types of cups, thick, thin, and long. One Car cup holder can be changed into two for use. You can adjust the adapter to fit a cup's diameter ranges from 3.0" to 5.9" and it fits most20 oz water bottles.
The cup holder has a base made out of a foam cushion that can not only reduce vibration but also stabilize the holder.
