This is a double cup holder for the 3rd row of the 1993-1997 Toyota Landcruiser. It does NOT fit the 91-92 Landcruiser due to it not having arms rests for the middle row. This cup holders hangs on the back of the 2nd row. There is no hardware or adhesive used. It does not effect the function of the middle row armrests or their movement. It can hang on either middle row seat allowing on of the middle row seats to be folded down without issue if desired. It is a very snug fit and will take some wiggling to slide it all the way down onto the middle row seat. It is designed this way to keep heavy drinks secure and prevent bouncing around. These are made of ABS plastic through the use of a 3D printer. They come in the factory tan and gray as well as a satin black. The cupholder can easily be removed at any time.
