Some problems of daily life have countless solutions. This is one. For this particular problem, there are endless solutions, some going back thousands of years. This particular problem has always had an element of danger, and this solution was supposed to be easy, durable, and safe. This was designed mostly for women, but that was a matter of fashion. Men would have also used this.

It was designed to make something else be the way it was when it was new. The holes on the tabs allowed it to be screwed down, at which point you could remove the handle. The wheels roll, and are a bit wobbly. They’re very loose, and not attached to each other. It’s possible to roll one individually. While in use, they don’t roll very much.

You can buy these new today, along with a variety of other solutions, but perhaps the most common solution to this un-revealed problem is our disposable culture.

Note: I’ve owned a few of these, but I always used them wrong! The video in the answer demonstrates correct usage.
