We offer antistatic brushes with carbon fibre or stainless steel yarn. In an independent test, KULLEN antistatic brushes were compared with the products of three other manufacturers. The results for us - outstanding! We were the only manufacturer to receive this assessment in all categories. The test included conductivity and dimensional stability.For example, KULLEN antistatic brushes used in laser printers exhibited no wear even after 400.000 pages. Yet further proof of our superb quality.
