Bought as hand luggage for air travel trolley. It is surprising for this price well finished and furnished. Many zippers and boxes ... The smell, which was criticized by some buyers was noticeable even with my trolley, but after a few days completely warped practically in the open air. From the crowds here the part moves at absolutely permissible maximum at most airlines, especially Ryan Air: 55 x 40 x 20, particularly the 20 cm can be easily exceeded in overload, because a built-in expansion fold yields and then also good 24 cm width result. How exactly does it take the airlines, I can not say. The weight is about 2.5 kg.
