This is an ace. suitcase. I purchased it from the manufacturer's official website. The size is 450 x 340 x 200 mm, with a capacity of 21L. It fits in small coin lockers. I believe it's from the Palisade series, but I apologize if I'm mistaken. Please refer to the photos to confirm. It's not a current model. The color is black carbon. I bought it about 3 years ago and have only used it a few times. I carefully cleaned the casters and exterior after each use. The interior is also very clean, with no stains or tears, so I believe you can use it comfortably. The casters are, as expected from Ace, very quiet when rolling. There are no defects, so you can purchase with confidence. For shipping, I will use simple packaging with bubble wrap and ship it on the weekend of the purchase date. I will not accept price negotiations, and I will delete any comments asking for a price reduction. Please consider it. Color: Black系 (Black-based) Carry-on size: S (up to 3 nights) Features: Carry-on, hard case, TSA lock Stains/tears: None
