When going on a trip, the cable and adapter of the smartphone or PC in the bag or the suitcase get out of the way and it becomes quite obstructive. We store them in this case together and carry them. Because you can see the inside, you can confirm the forgotten thing without opening the case. Especially since the plug of the adapter does not touch other things, it will not hurt your valuables. We are planning to compact other handheld items using the same case.
