Armrest Box for Cars Without a Mechanical Handbrake Compatibility and fit: designed for vehicles that do not have a mechanical handbrake. A clear 1inch gap between the seat and the center console is required; if this gap is not present, this product is not suitable. Rest your arm and wrist: provides a comfortable resting surface for the driver's right arm and wrist, and for the passenger's left arm and wrist, helping reduce fatigue on long highway drives. Extra storage space: creates additional room to store daily essentials such as cash, cards, and a phone, helping keep the cabin organized and items within easy reach. Easy to install and remove: installs without modifying or damaging the original car structure, and can be removed or reinstalled quickly as needed. It does not interfere with the operation of the parking brake. Use scenarios Long highway trips: the driver can rest the right arm and wrist for better comfort on extended drives, while a passenger can rest their left arm comfortably as well.

Shared vehicle use: both driver and passenger benefit from a stable resting place and convenient storage, improving overall comfort and accessibility during mixed driving tasks.
