The Wahl® USA Lithium Ion® mens beard trimmer contains the most advance rechargeable battery technology available. It's lighter weight, has almost no charge loss in storage, is environmentally smart, and has no memory issues. Best of all, it provides 3x the run time (3 hours), 2x the torque, a 1- minute quick charge for 3 minutes of use and 1-hour full charge which standard NiMH/NiCad trimmers cannot do. This Wahl beard trimmer kit includes a trimming blade attachment for beard and mustache trimming. A precision detail head for trimming small detail areas around the mustache, chin, goatee, & eyebrow areas. A rotary trimming head for hygienic trimming of ear and nose hairs. You will have more control and better precision trimming with our no slip comfort grip. The powerful motor allows for easy, smooth trimming and detailing. Wahl’s self-sharpening precision blades stay sharp longer and continuously sharpen over time, just oil between every few beard trims to increase the longevity of your trimmer motor and blades. Included in the 14-piece grooming kit are 3 interchangeable trimmer heads, 3 guide combs ranging in size from 1/16” - 3/16", a 10 position guide comb (12mm - 20mm), a 6 position (1/16” - 1/2"), beard comb, cleaning brush, blade oil, blade guard, soft case, wall charger, and instruction book. When not in use always unplug charger from unit. Note: We test our clippers and trimmers for cutting performance with a hygienic fiber. Any fiber you may find on the clipper is not hair but a result of this process and can be simply wiped off.
