The idea is quite good, but it takes up too much space in actual use. For example, if you could have put 10 square suitcases, you might not be able to put 10.
When placing clothes and pulling, the form of placing clothes is different. One side of the surface is flat, which is used to lay clothes flat. When pulling, the angle is inclined. The figure is not inclined. It is my mistake. When not pulling, the balance can be preserved. The wheels on both sides are horizontal, not vertical. There are other deficiencies that can be pointed out. Accept with an open mind. Thank you!
Can you guess why suitcases are square innovations don't mean they can go against science?

It's fun, but the balance problem when walking can explain it.
