Wahl Professional Animal's Bravura Lithium Pet Clipper combines the power and durability of lithium ion battery innovation with Wahl's adjustable 5-in-1 blade to give groomers, animal professionals, and pet owners everything needed in a lightweight cordless clipper. The five blades adjust to sizes #9, #10, #15, #30, and #40, offering great variety in your cuts. The Bravura's rechargeable lithium ion battery has a 90-minute cordless run time and will operate at full power until the battery is completely depleted.

Ergonomically designed to fit comfortably in your hand, the Bravura is lightweight--weighing only 8.8 ounces--to prevent wrist fatigue while the grip surface provides control without sacrificing comfort.
