The Wahl Beret Lithium Ion Trimmer is designed to be modern in its every facet and contribute better functionality to anyone who uses it. The aforementioned Lithium Ion battery is perfect for busy environments with it never losing charge while switched off unlike most other batteries available. Using a blade that cuts to a length of 0.4mm, the trimmer includes plenty of attachment combs so you can have complete styling freedom while cutting. The blade is another example of the company’s innovation, being completely rust resistant so its chrome plated, grinding technology is never diminished over time
