Using the Dual Spinner Wheels
Each suitcase is equipped with four dual spinner wheels, providing 360-degree rotation for effortless mobility in any direction.
- For smooth movement, push the luggage upright on all four wheels.
- Avoid dragging the luggage on two wheels for extended periods, as this can cause premature wear on the wheels.

Maintenance
- Cleaning the Shell: Wipe the PC+ABS hard shell with a soft, damp cloth and mild soap. Avoid abrasive cleaners or solvents that could damage the finish.
- Zippers: Periodically check zippers for debris. If they become stiff, apply a small amount of zipper lubricant or wax.
- Wheels: Inspect wheels regularly for tangled hair or debris. Clean them gently with a brush if necessary. Avoid exposing wheels to excessive dirt or sand.
- Handles: Ensure the telescopic handle extends and retracts smoothly. Do not force it if it gets stuck.
- Storage: When not in use, store luggage in a clean, dry environment, preferably nested inside each other to save space.
