With this practical door box set, you can create additional storage space in all doors of your Model 3 or Y. The boxes are placed between the door opener and the rest of the armrest, creating space for small items such as keys, handkerchiefs, sunglasses, smartphones or other small objects that would only slide back and forth in the lower door boxes. Due to the perfect fit, they blend in well with the design of the doors. Installation is quick and easy. The set consists of 4 boxes, 2 each for the front and rear doors.
