Cup-Holder Expander Adapter with Expandable-Base for Car - All Purpose Multifunctional Car Cupholder x2

A "cup holder expander adapter with an expandable base" is an accessory for your car designed to hold oversized cups and bottles, such as large water bottles and mugs, that don't fit in standard cup holders. The adapter's base expands and retracts to fit snugly within your vehicle's original cup holder, while an adjustable collar or arms hold your drink securely in place, preventing spills and providing stability while you drive.
