Review on 🧹 Versatile 9.8-Inch Nylon Tube Brush Set: Ideal for Glasses, Straws, Keyboards, Jewelry, Antistatic, Pipe Cleaning - 12-Piece Variety Pack by Chad Overturf

I expected these to be disposable but they are durable, well made and hold their shape. What a pleasant surprise in their quality. The only reason I don't give 5 stars is that their tip is on the long side (but they are even covered in rubber on the tip!) so using them on blind holes is a little disappointing. However, at this price I will buy another set and try trimming back or bending the ends. Let's see if the top design is crucial for their performance. The size selection is very good. I use them to clean drilled, machined and cut holes in metal.
