3.1 Setting the TSA Combination Lock
Your luggage comes with a preset combination of 0-0-0. To set your personal combination:
- Ensure the lock is set to the default 0-0-0.
- Locate the small reset button (usually recessed) next to the dials. Use a pen or pointed object to press and hold this button.
- While holding the reset button, set your desired 3-digit combination by turning the dials.
- Release the reset button. Your new combination is now set. Remember your combination as there is no master key.

4. Operating Instructions
4.1 Extending and Retracting the Telescopic Handle
To extend the handle, press the button located on the top of the handle and pull upwards. The handle has 3 adjustable levels. To retract, press the button and push downwards until it is fully stored.
4.2 Using the Spinner Wheels
The luggage features 360-degree spinner wheels for effortless multi-directional gliding. For optimal maneuverability, push the luggage upright on all four wheels. For rougher surfaces, tilt the luggage and pull it on two wheels.
4.3 Packing and Organization
Utilize the internal cross straps to compress your clothing and prevent shifting during transit. The zippered mesh pocket is ideal for smaller items, toiletries, or documents, keeping them separate and easily accessible.
5. Maintenance
5.1 Cleaning the Exterior
Wipe the hard shell exterior with a soft, damp cloth and mild soap. Avoid abrasive cleaners or solvents that could damage the surface. For stubborn marks, a gentle cleaner designed for plastics may be used.
5.2 Cleaning the Interior
The interior lining can be spot cleaned with a damp cloth and mild detergent. Allow to air dry completely before closing the luggage to prevent mildew.
5.3 Wheel and Handle Care
Periodically check the wheels for any debris or hair that might impede smooth rolling. Clean as necessary. Ensure the telescopic handle extends and retracts smoothly. Avoid forcing the handle if it feels stiff.
6. Troubleshooting
6.1 Lock Not Opening/Closing
Ensure the correct 3-digit combination is entered. If you forgot your combination, unfortunately, there is no master reset. You may need to try all possible combinations (000-999) or contact a locksmith.
6.2 Stiff or Stuck Telescopic Handle
Check for any obstructions in the handle mechanism. Ensure the release button is fully depressed when extending or retracting. Avoid applying excessive force.
6.3 Wheels Not Rolling Smoothly
Inspect the wheels for tangled hair, lint, or other debris. Carefully remove any obstructions. If a wheel is damaged, contact customer support for assistance.
