Otis Technology Bronze All Purpose Brushes (Select Your Style)

These are great brushes. I use them with cleaning motorcycle parts and guns. They dp leave a brass colored residue sometimes. They pack well and fit in tight spaces. The large brush and small brush on the other is very functional. Easy to use and the plastic is not fragile/ they are the right "bendadility" to clean well.

Great brushes for cleaning carbon buildup on the internal parts. Great value for the price.

I ordered these gun tool brushes not for gun cleaning, but general cleaning at home. In particular I use it to clean a Rancilio Rocky coffee grinder. These brushes are made in USA and appear to be genuine brass, not the brass colored stuff sold for cheap. A little more expensive, but a bargain in the end. For my grinder, I was using them to clean the brass threads of the grinder assemblies, which get gummed up with use. The two different ends work great for getting into different spaces, so I’m impressed. They do bend if you push too hard, given they are brass, but they are much more solid in hand than the cheap brushes. The pack will last me the rest of my life, given the quality.

Excellent brushes! Worth getting in bulk and throwing away when worn out rather than using it past its life expectancy and having bristles fall into your gun.

Well made and very useful. Worked well for the needed application.

Like all other Otis products, they are well made and designed to do the job. I really like the two ended ones with a large and small portion to get into spaces. I use these bronze bristled brushes primarily to clean guns. I reach for these only when the nylon ones is not getting the job done. Only flaw I noticed was the fact these come packaged bulk in a single plastic bag with no protection from being crushed. Most of the brushes in my shipment have some damages to the bristles.

Great for cleaning out those precious high carbon steel components, They were a good price and have lasted well. Would buy again.

Arrived in good condition. Great item
