Review on Variety of Colored Fiberglass Scratch Brushes by Jason Camarillo

Works well but wears out quicker than expected. No matter how expensive it is, there should be several gas stations for it. I picked this one out of the cheaper ones based on the reviews, but was surprised that it really didn't feel like a $12 tool. value for money? Fur. It says "Made in Germany" but now I'm wondering if it's a Chinese fake? However, the quality of the tips is far superior to the brush that came with this pen. This will quickly fall apart and turn into fiberglass dust. The stock parts feel much more durable and I notice far less dirt and fiberglass residue with use. For $12 they definitely should have included a better brush insert and at least one refill.
