These Wahl Optimised Black Attachment Combs (#1-8) are designed to increase the cutting length of your clipper, and are accompanied with blade oil and a cleaning brush. Optimised for increased strength, these guide combs are manufactured with engineering grade polymer material to increase guard teeth thickness. With attachment clips 90% bigger and enhanced for the Clipper blade, our SECURE-FIT™ technology gives you more durability and superior comfort. Not only are these attachment combs easy to attach and remove thanks to the large easy-to-see size markings, but the high-gloss finish enables improved feeding of hair through the guards resulting in exceptional cut quality. Enhancing ease-of-use and manoeuvrability, increasing the tip radius and shortening guard teeth gives you greater visibility and more reliable results. This set contains grades #1 – 8. Includes No. 1 – 3 mm, No. 2 – 6 mm, No. 3 – 9 mm, No. 4 – 13 mm, No. 5 – 16 mm, No. 6 – 19 mm, No. 7 – 22 mm, No. 8 – 25 mm.
