The Eisco Labs Tapered Bristle Cleaning Brush features medium-soft fiber bristles with a cotton yarn tip, ideal for scrubbing narrow-neck bottles, test tubes, pipes, jars, vases, measuring cylinders, and laboratory glassware. The cotton tip allows you to clean corners and crevices without scratching glass surfaces. A twisted stainless steel wire handle with a looped end provides corrosion resistance, moderate flexibility for shape adjustment, and easy hanging for storage. Total length is 8.5", with a 3.75" bristle section that tapers from 1" down to 0.5" in diameter and a 4.75" handle. Fits inside objects with diameters between 0.5" and 0.75".
