High quality brush
Works great for obsessive cleaning of small boulder holds. I only give it four stars because I'm biased towards the feel of the plastic Lapis brushes - I just prefer the feel of those in my hand. However, this brush is much more durable, much larger, the bristles tend not to fall out (like with some other brushes). I wrapped mine in reflective tape so that I wouldn't lose it, as it tends to wander off. Very high quality for the price.
Rating: 4 stars
