I am exercising with dumbbells from an unnamed company.

My main exercise equipment is dumbbells, but they are not from a particular brand. Since when have they been at home?

They are dumbbells whose existence I cannot confirm; there is a light 1-kilogram one and a slightly heavier 5-kilogram one.

First, I took only one photo, but there are two available so that one can be used on each side.

The 1-kilogram one feels a bit light, but it's quite good to hold when doing stretching, right? I have weak arm strength, so even the 5-kilogram one is...

Because it is sufficiently heavy, this is mainly used for strength training. It's not a well-known or high-quality item, but.

It is sufficiently helpful for exercise.
