Regarding bringing in a WiFi BOX when using Korean airlines

Korean airlines may prohibit storing mobile batteries in the on-board baggage storage rack.
The self-service Wi-Fi rental "WiFiBOX" provided by our company has a mobile battery function and uses lithium-ion batteries. This is subject to regulations, so please be careful when using it.
If you violate the regulations, your bag may be confiscated or disposed of, so please check the rules for carrying your bag set by the airline you plan to fly on.
