Query: Hmmm.....

Without a complete description or the ability to zoom in on the picture I assumed these were sythetic fiber and that there was a very small thin "brush" in the kit. The brushes are natural fiber and the fibers break loose very easily. The twisted wire ends are just cut off, not smoothed or deburred, which could lead to scrathes on the inner bores of your equipment. The small very thin "brush" is actually just a wire. These brushes are all larger than I expected, the "toothbrush" is about 7.5" long (for reference) and the smallest diameter brush is 7/16" diameter, a little too big for many of the smaller orifices in most spray equipment. Not too expensive, but not what I was looking for.
