3. Setup Instructions
3.1 Unpacking
- Carefully remove all suitcases from their packaging.
- Remove any protective films or tags.
- Inspect each suitcase for any signs of damage. If damage is found, contact customer support immediately.
- The smaller suitcases are nested inside the larger ones for shipping. Open the largest suitcase to access the others.
3.2 Setting the Combination Lock
Your suitcase comes with a preset combination of 0-0-0. To set your personal combination:
- Ensure the lock is set to the default combination (0-0-0) and open the lock.
- Locate the reset button (a small, recessed button, usually on the side or bottom of the lock). Use a pen or a pointed object to press and hold this button until you hear a click.
- While holding the reset button, set your desired 3-digit combination by turning the dials.
- Release the reset button. You should hear another click, indicating the new combination is set.
- Scramble the dials to test your new combination. Ensure it opens only with your chosen code.
Important: Remember your combination. There is no master key or override function.
4. Operating Instructions
4.1 Using the Telescopic Handle
- To extend the handle, press the button located on the top of the handle and pull upwards.
- The handle can be locked at multiple heights for comfortable use by travelers of different statures.

4.2 Using the Spinner Wheels
The 360° spinner wheels allow for effortless movement in any direction. You can push, pull, or roll the suitcase alongside you, reducing strain on your arm and shoulder.
- For smooth gliding, ensure the suitcase is upright on all four wheels.
- Avoid dragging the suitcase on only two wheels for extended periods, as this can cause uneven wear and damage to the wheels.
4.3 Packing Your Suitcase
- Utilize the elastic cross straps to secure clothing and prevent shifting during transit.
- Place heavier items at the bottom (near the wheels) to maintain balance.
- Use the zippered compartment and mesh pocket for smaller items, toiletries, or documents.
- Do not overpack the suitcase, as this can strain zippers and seams, and may exceed airline weight limits.
4.4 Locking and Unlocking
- To lock, align the zipper pulls with the lock mechanism, enter your 3-digit combination, and press the release button (if applicable) to secure the pulls. Scramble the dials to lock.
- To unlock, enter your 3-digit combination and press the release button to release the zipper pulls.
5. Maintenance
5.1 Cleaning the Exterior
- Wipe the ABS shell with a soft cloth dampened with mild soap and water.
- Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface.
- Dry thoroughly with a clean, dry cloth.

5.2 Wheel and Handle Care
- Periodically check wheels for debris (hair, lint) and remove them to ensure smooth rolling.
- If wheels become stiff, a small amount of silicone-based lubricant can be applied to the axle.
- Ensure the telescopic handle extends and retracts smoothly. Do not force it if it gets stuck.
5.3 Interior Care
- Wipe the interior lining with a damp cloth and mild soap if necessary.
- Allow the interior to air dry completely before closing the suitcase to prevent mildew.
5.4 Storage
When not in use, store the suitcases in a clean, dry place. The stackable design allows for compact storage by nesting the smaller suitcases inside the larger ones.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Combination Lock will not open. | Incorrect combination entered or combination forgotten. | Ensure the correct 3-digit combination is entered. If forgotten, there is no master key; you may need to try common combinations or contact customer support for advice (though typically, forgotten combinations cannot be reset without the original code). |
| Telescopic Handle is stuck or difficult to extend/retract. | Debris in the mechanism, bent handle tubes, or excessive force applied. | Check for any visible obstructions and remove them. Ensure the button is fully pressed. Do not force the handle. If bent, contact customer support. |
| Wheels are not rolling smoothly or are jammed. | Debris (hair, dirt) caught in the wheels, damaged wheel, or lack of lubrication. | Clean any debris from the wheels. Apply a small amount of silicone lubricant to the wheel axles. If a wheel is visibly damaged, contact customer support. |
| Zippers are difficult to move or snag. | Fabric caught in the zipper, or zipper teeth are misaligned. | Carefully pull any fabric away from the zipper path. Apply a small amount of zipper lubricant (e.g., wax or silicone spray) to the zipper teeth. Avoid overpacking. |
