This is an awesome little addition to help with storage in your Tesla. With a strong velcro backing, it'll basically stick wherever there's carpet. We have ours in the front footwell, stuck on the side of the center console carpet. You can also put it in the trunk, or in front of the rear seats. Great for storing things like sunglasses, charge cards, etc. Made from high-grade flexible silicone, it's washable if needed, unobtrusive, and has a flap to cover & protect the contents.
Internal dimensions are 7.5" x 3" x 1.3" (195mm x 75 x 33). The front-back dimension can vary a little to expand for larger sunglasses, since it's made from silicone.
