FlexCup Duo Expander is a universal adjustable cup holder designed to fit securely into the original cup holder of your car and create extra space for larger bottles, mugs, or two drinks at once. The base expands by twisting the top section, allowing it to adjust from 2.5 to 3.75 inches and fit a wide range of vehicles, including cars, SUVs, trucks, vans, boats, golf carts, and more.
The dual U-shaped openings allow you to place mugs with handles without tilting or squeezing them, and the rubberised base keeps cups stable while reducing noise and preventing scratches. The offset design helps the holder avoid contact with the gear shift, console lid, or dashboard buttons, making it compatible with more interior layouts.
Installation is simple: insert the expander into the existing cup holder and twist to lock it in place. Once secured, it can safely hold bottles from 18 to 40 oz, travel mugs, thermoses, and wide drink containers up to 3.4–4 inches in diameter.
FlexCup Duo Expander is a practical upgrade that adds flexibility, extra storage, and better convenience to your car’s interior.
