Utile 7 Pcs Lab Cleaning Brush Set, 7 Sizes for Different use, one Beaker Brush, one Buret Brush, one Cylinder Brush, Four Tube Brushes, 5500.9901.1.

Upfront disclosure: I received this item through the Amazon Vine program for review.I have been working in labs since I was 15, and for the past 20 years I have taught high school chemistry. We use bottle brushes every time we do a lab and these ones are very similar to the ones I actually use in my labs. They are solid and seem to have standard construction. They definitely get the job done and well.

A great set of brushes, high quality bristles, 7 in all. They are called lab brushes, but I bought them for my kitchen and office - a size for every task. I particularly like the large Beaker Brush, big and sturdy and goes in thermoses, vases, and other difficult to clean items with its good-sized handle and U-shaped brush. A great gift idea!
