The edges are protected by an aluminum alloy, and the suitcase is firmly assembled with three rivets, extending the life of the suitcase and achieving smooth opening and closing without snagging. ② The hard-type body is excellent in water and dirt resistance, as well as impact resistance. Furthermore, the frame-type opening and closing method excels in security. 【USB + Drink Holder + Side Luggage Hook + Smartphone Stand Multi-functional Carry Case】 ① Equipped with a USB charging port, you no longer have to worry about your mobile phone or iPad running out of power, and the charging port has a waterproof cover. ② A foldable cup holder is installed on the back of the suitcase, allowing you to easily take out and put in drinks, bottles, cups, umbrellas, etc. A smartphone stand is attached to the handle of the suitcase, preventing you from looking down at your smartphone or iPad to avoid neck pain. There is a side hook on the side to reduce the burden on your travel companion. 【Stopper & TSA Lock Equipped｜Safe for Travel and Security】 The casters are equipped with a one-touch stopper function, ensuring safety on trains and slopes by preventing the suitcase from rolling away on its own.
