A total of 14 doors were constructed in a one-way (intersection).
If there are 14 doors, they usually work two ways.
This is because it can be folded, opened, and closed easily, giving free passage regardless of size.​

Rain, wind, snow... because even if you open the door and close it completely, you can see inside and out. And you can get sunlight without any interference from fine dust.
Also, because you can see from the inside, you can safely and trust the vehicle.​

We prefer clean places to dirty places, so we can arrange things well and see the inside of clean stores from outside, so we can welcome customers who come to see us.
