Purchased on Amazon. Used twice for a 2-night, 3-day trip. It's multi-functional, stylish, and very easy to use. I am considering purchasing a new carry-on case, so I am listing this one for sale. I want to sell it, so I will consider price negotiations. (※Due to shipping and packaging, I may not be able to accommodate significant price reductions.) 【Design】Aluminum frame 【Material】Body: Polycarbonate Carry bar: Aluminum alloy 【Features】Dial lock (TSA lock) Cup holder Smartphone holder Luggage hook USB port Wet/dry pocket Auto-return handle Corner protector
