What is the purpose of using a suitcase?
There are various reasons, I think. I love traveling overseas and usually go on trips during long vacations. I use suitcases mainly for personal travel, not for business purposes. The basic shape is the same, so whether it's for personal or business use, it's the same. It's easy to understand if you interpret it as a bag to carry the necessary items for a few days' stay.
How do you decide on the material and size? What did you choose?
The body material of suitcases can be broadly divided into hard and soft types. As the name suggests, hard types are made of rigid materials such as aluminum, polycarbonate, and ABS resin. Soft types are made of mainly soft materials such as nylon and polyester that can be deformed.
It is also recommended to choose a suitcase that fits your body, depending on the amount of luggage. Size and weight are important factors, as a suitcase that is too small may require you to tilt your body when pulling it. However, it is also important to consider the ease of movement when pulling it.
