Maintenance
Cleaning the Hard Shell
To clean the exterior hard shell, wipe it down with a soft, damp cloth and a mild soap solution. Avoid using abrasive cleaners or harsh chemicals, as these can damage the polycarbonate material. Rinse thoroughly and dry with a clean cloth.

Wheel Care
Regularly inspect the spinner wheels for any accumulated dirt, hair, or debris. Clean the wheel axles as needed to ensure smooth rotation. If the wheels become stiff, a small amount of silicone-based lubricant can be applied to the axles.
Zipper Maintenance
Keep zippers clean and free of obstructions. If zippers become difficult to operate, apply a small amount of zipper lubricant or a silicone-based spray to the teeth.
Interior Cleaning
The interior lining can be spot-cleaned with a damp cloth and mild soap. Allow the interior to air dry completely before closing the luggage to prevent mildew.
Troubleshooting
- Telescopic Handle is Stuck: Gently pull and push the handle while pressing the release button. Check for any visible obstructions or debris in the handle mechanism.
- Wheels are Not Rolling Smoothly: Inspect the wheels for any tangled hair, lint, or other debris. Clean the axles thoroughly. If the issue persists, a light application of silicone lubricant may help.
- TSA Lock Not Opening: Ensure you are entering the correct 3-digit combination. If you have forgotten your combination, you may need to reset it following the instructions in the 'Setup' section.
- Zippers are Sticking: Check for any fabric caught in the zipper teeth. Apply a small amount of zipper lubricant or a silicone spray to the zipper teeth and gently work the zipper back and forth.
