I. Material & Protection: Rugged Durability for Impact Resistance
The luggage shell features a composite structure of high-hardness ABS, ABS+PC, and PC with aluminum alloy edging. The main body is made of military-grade impact-resistant PC, whose toughness is 1.5 times that of ordinary PC, capable of withstanding rolling pressure of 100kg. Thickened metal corner guards are added at the four corners of the shell to further enhance impact resistance, adapting to complex scenarios such as long-distance checked baggage and outdoor jolts, effectively reducing the risk of shell deformation and cracking due to collisions.
The surface is coated with a high-gloss scratch-resistant finish paired with a three-dimensional vertical texture. It not only improves the visual texture of the shell but also resists scratches and wear during travel, maintaining a bright and new appearance even with long-term use. Meanwhile, the coating has a slight anti-fingerprint effect, making daily maintenance more convenient.

II. Structure & Mobility: Smooth Maneuverability for All Scenarios
The mobility system balances stability and flexibility. Equipped with eight silent universal wheels (for some large-size models), it adopts high-elasticity rubber treads and dual-axis bearings, producing noise below 35 decibels when rolled. Supporting multi-angle movement such as horizontal and diagonal directions, it can be maneuvered "smoothly" on surfaces like airports, high-speed rail stations, and gravel roads, easily pushed with one hand. The telescopic rod is made of aviation-grade aluminum alloy, offering 4-6 height adjustments to fit people of different heights. With a wobble amplitude of less than 0.8cm when extended, its durability and stability are far superior to ordinary rods.
Widened handles are installed on the top, side, and bottom of the shell. The grip area is made of non-slip rubber material, making it more labor-saving when carrying heavy items for short distances and adapting to picking and placing needs in different scenarios.

III. Storage & Safety: Practical Experience with Detailed Upgrades
The storage space is designed to balance capacity and classification efficiency. The main compartment adopts a "double-opening + partitioned layer" structure. Luggage of 20-28 inches can accommodate clothing and daily necessities of corresponding sizes. The inner side is equipped with elastic mesh pockets, zippered document bags, and digital accessory slots to achieve refined classification of items and avoid clutter. Some models are equipped with a hidden expansion layer, which can increase storage space by about 20% when opened, coping with the temporary increase of luggage.
Safety configurations provide comprehensive protection. Equipped with a TSA customs combination lock + side-opening privacy lock, it not only meets international air transport standards (avoiding forced opening during checked baggage) but also can independently lock the side compartment's privacy area to protect the safety of documents and valuables. The lock body is made of anti-pry metal material, with a service life of over 6 years, suitable for high-frequency travel needs.

IV. Aesthetics & Adaptability: Luxury Style Compatible with Multiple Scenarios
The light blue color with metal corner guards combines freshness and luxury texture. The light blue color scheme is suitable for scenarios such as leisure vacations and students returning to school, appearing more lightweight and energetic visually. The combination of metal corner guards and silver hardware enhances the delicacy of the shell, while adapting to the formality of business trips, easily suitable for both men and women.
The series supports "multi-size combination" (20-inch carry-on + 24/28-inch checked luggage), meeting the needs of different travel scales such as single short trips and family long-distance travels. It is a highly adaptable equipment that balances daily use, business, and travel scenarios. Moreover, the luggage can be stacked for storage, saving home space when not in use.

In summary, this light blue luggage with metal corner guards takes "impact-resistant and durable, smooth maneuverability, refined storage, and luxurious aesthetics" as its core advantages. It solves the pain points of traditional luggage such as being easy to damage, difficult to maneuver, and messy storage, and improves travel experience through material and detail upgrades. As a cost-effective travel essential that combines rugged performance and aesthetic design, it perfectly meets the modern travel demands of "complex scenarios + refined experience."
