Otis TechnologyNylon AP Brushes (Select Your Style)

These things are the toughest brushes I've ever seen. They work excellently scrubbing at the toughest jobs with no visible damage to either the brush or the object. The small end is even tougher and able to get into the smallest of crevices to clean. I keep one in my backpack and gave the rest out to friends. This one brush has lasted 6 months with multiple uses, and still looks new. No other brush is even close to these.I give Hercules' toothbrush a solid 10/10

These brushes are awesome for cleaning in tight spots and cleaning off gunk. The price of these is very good for the value and they make each cleaning very easy. They hold up to Solvents and can be cleaned for next use!

With working on a CNC machine and cutting out pieces of wood and cutting small holes it can be difficult to get into those small spaces and try to get out little fibers of wood that may be still attached. These brushes have been very helpful in brushing those out or so that they come up and I can sand them off. They came in a basic zip lock back which is very convenient. I just take one out and put the rest in my drawer for when I need them. The bristles are very firm and able to get into those tight spots and brush out those bits I am looking for. They make for easy clean up on my wood. I haven't had any issues with bristles getting bent or losing their sturdiness. The main handle is is easy to hold like a pencil. This is a very well made product.

They make several different kinds of brushes for cleaning firearms. Soft nylon which is usually white, Kors nylon which is blue and then bronze copper brass and steel. I probably use blue nylon for 90% of my cleaning applications. They are hard enough to really get through all but the most stubborn carbon deposits and soft enough that they will not damage the finish of your firearm.There are basically two brush designs, one with a curved brush head and one with a flat straight brush head with a notch in the bristles. I find the flat notched version to be much more agile for getting into the nooks and crannies of a handgun. So I like the design of these and the materials are good quality at a reasonable price. These brushes are quite durable I can probably do about 150 cleanings before I would need to change brushes. Contrast that to my bronze brushes which probably last no more than 10 cleanings because the wire bristles get easily bent out of shape.These brushes have a smaller tip on the end of the handle to let you get into smaller areas like cleaning the chamber. Are used to use toothbrushes but since I discovered blue nylon they have been my go to brushes and these are my go to brand.The pics show my brush pretty dirty up after about 40 cleanings and then what it looks like when I rinse it out with just hot water. Also showing the precision brush on the handle and there’s a white nylon brush that shows the other curved design of the brush heads in contrast with the more narrow straight design which these have and I find much more practical.

These are not forever tools… just like a toothbrush. They break or get mangled, just toss and go to a new one. They work, what more does anyone need?

The small brush and bigger brush sections, make these brushes very versatile! I've been using these brushes on cleaning automotive parts, and they've held up well to all the different tasks being thrown at them! Good value for cleaning older tools as well!

I have used Otis products for many years and they are of good quality and long lasting. These brushes are good for scrubbing away carbon buildup.. I will share this 10 pack with friends and family.

Nice brush with strong bristles. It will last for quite long time.
