The wheeled board rotates around the connecting joint and retracts into the main body. Built-in magnets secure the board, preventing accidental opening or wobbling. The connecting joint is made of 1680D reinforced nylon and features reinforced stitching. The magnetic force is moderate and there is a frame, so the impact on electronic devices is extremely low.

Yes. The soiled casters and surrounding areas are covered by the wheeled board as soon as it's retracted. Since they don't directly touch your clothes, you can rest assured about hygiene.

Because of the built-in board, it's slightly less spacious than a typical backpack. However, the thick shoulder straps and back cushioning are designed to distribute the load and minimize strain. And when you get tired, you can roll it on its wheels, so there's no need to carry it on your back for extended periods.

The shoulder straps can be stowed in the back pocket, preventing them from touching the ground. To prevent damage to the shoulder straps from dragging, please be sure to store them in the pocket when rolling the bag.

By extending the casters, the bag can stand on its own. When you put down the backpack, the bottom of the bag does not directly touch the ground, so you can set it down without worrying about dirt. *Please note that the bag does not stand on its own when the casters are retracted.

Yes, it's possible. You can replace them yourself in about 15 minutes using the separately sold "Caster Replacement Kit."
