It can be expanded from 16 inches (about 40 cm) for carry-on to 26 inches (about 66 cm) when returning home. It is fully compatible with the cabin sizes of major international flights such as JAL and ANA, so you don't have to worry about additional charges even if you pack plenty of souvenirs. With a thin design that fits neatly on the mesh shelf of the Shinkansen, it is a "magic suitcase" that is perfect for moving around Japan. [High-quality body & reliable zipper] Adopts a highly durable hard body that combines lightweight and highly elastic ABS resin with PC (polycarbonate) resin with excellent impact resistance and thermal insulation. It can be used with confidence for both everyday use and long trips. The main zipper uses Japan's world-class zipper, which greatly reduces problems such as zipper derailment and opening. Plus, the fully waterproof construction ensures that the contents are well protected even on rainy days. [Quiet design for comfortable movement] Equipped with 360° rotating and completely silent casters that can be rolled smoothly even in the tatami corridors of hot spring inns. The quiet level is 25dB, which is quieter than a whisper. You don't have to worry about the sound when moving, and you can use it in public places with consideration for your surroundings. The handle is three-stage adjustable and designed to match the average height of Japan people. It reduces the strain on the arms even during long travel. [Plenty of storage & smart design] Made of special materials that are thin and lightweight, yet highly durable. The interior is equipped with dividers on both sides for easy organization to prevent clutter of luggage. The unique storage design fits each size perfectly even after resizing, allowing you to utilize space without waste. [Equipped with a secure TSA lock] A TSA dial lock is standard equipment that is essential for overseas travel. You can leave it with confidence during security checks. You can change the size from 40L (carry-on size) to up to 72L (for one week's worth of luggage) with one touch. This is a next-generation suitcase that can be freely adjusted according to the destination and luggage volume.
