Trunk Luggage Structure (3:7 Split Design)
Trunk-style luggage typically features a dual-compartment opening structure, where the suitcase is divided into two sections — a deeper main compartment and a secondary packing area.
This balanced design allows travelers to separate belongings more clearly, making it easier to organize clothing, shoes, and travel essentials.
Because the packing weight is distributed across both sides, trunk luggage often feels more stable and secure when fully packed, especially during long check-in journeys.
The deeper compartment also helps accommodate bulkier items while keeping them protected throughout transit.
Top-Open Luggage Structure (1:9 Vertical Packing Design)
Top-Open luggage is designed with a larger main packing compartment and a slimmer lid section, creating a layout that supports vertical packing.
This structure allows travelers to access belongings quickly without fully opening both sides of the suitcase.
It is especially useful in tight hotel rooms, train aisles, car trunks, or crowded airport environments, where space to lay the suitcase flat may be limited.
By offering a more continuous interior depth, Top-Open luggage provides greater flexibility when packing larger or taller items.
