No instructions. Tips seem hard to change, and unsure as no instructions.

Very nice set of scratch brushes. Very compact and work well.

If you work on electronics, this is a must have.

I have used a these a few times and they done the job I expected of them. They definitely helped reaching areas that I could reach with my fingers.

I bought these brushes to clean crevices and tight spaces where a regular brush wont fit. The brass and steel bristles are very weak. They are virtually worthless for cleaning. I havent tried the nylon ones.

What can you really expect for $4.25 each, have low expectations and just consider them disposable....

They are of the quality that you would get as a prize from Chuck E. Cheeses.

One of the tools came broken right in the package, it was glued up wrong and unusable. the other tools were cheap junk that will probably break the first time I use them. poor manufacturing, bad quality control and cheap materials. Ive seen better made stuff at the dollar store.

It will do the job, but they feel really cheap, the pouch is cheap, and the knob is odly tight and gets stuck.

Product does come with two metal plus one plastic bristle brush pens and replacements. The product is cheaply made so taking the existing brush to put a replacement literally destroys the pen itself so it is pretty much impossible to use that replacement with the existing pen. The brushes are also very weak and flimsy so they dont offer much brushing. I gave it three stars because the metal brushes are more useful but not much.
