The idea is great, but the product is improved. I bought the wine bag for carrying 12 bottles of claret in the process, with several changes of matches and repeated handling. In wanting to secure the full luggage (about 18 kg) with a tensioner travel devil, I realized that it was distorted by the compression of attachments, for the simple reason that the interior space is more important than the need The cashier of 12 bottles. To actually stalling the internal fund, it is necessary to fill a difference in thickness which is six centimeters per edge (3 cm per side), which is not easy when one is not handy. Here is the solution: Get two extruded polystyrene plates of 125 cm x 60 cm x 3 cm, cut six sides with a cutter, the size of each side of the box, put one at the bottom, insert the body and chock it to end the 5 remaining faces before closing the bag. Attention because of the extra thickness caused by the wheels, you will have to cut at right angles to the lower corners of the face corresponding polystyrene, so that it can be properly pressed between the inner box and the envelope wine luggage. Once these modifications, your precious bottles no longer fear anything. Good luck.
