I am looking to clean out some space in my garage. I have 4 Enkei boxes, big enough to fit a 17 x 9 wheel. I also have the boxes that my Recaro seats came in which are huge. I'd have to check, but I believe they were double boxed. I'd say the rough measurement is 28 x 28 x 40. Perfect for shipping or storing oversized items or just making your kids/pets really happy. Local pickup in Tucson.
