How caster storage technology works

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 with reinforced stitching. The magnetic force is moderate and there is a frame, so the impact on electronic devices is extremely low.

Will it stain your back?

It generally stays clean. Casters and surrounding areas that have dirt on them are covered by the wheeled board as soon as they are stored. This also provides peace of mind from a hygiene perspective, as it does not directly touch clothes.

How comfortable is it to carry?

Since it has a built-in board, it's slightly less spacious than a typical backpack. However, the thick shoulder straps and back cushion distribute the load, minimizing the burden. If you get tired, you can roll it with the carry handle, so there's no need to carry it on your back for extended periods.

When you roll it, will the shoulder straps touch the ground?

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.

Does the bag stand on its own?

The bag stands upright when the casters are extended. When you set the backpack down, the bottom of the bag does not directly touch the ground, so you can place it down without worrying about dirt. *Please note that the bag does not stand upright when the casters are retracted.

Can the casters be replaced?

Yes, you can. By using the separately sold "Caster Replacement Kit," you can replace them yourself in about 15 minutes.
