With the Wahl Color Pro Cordless Lithium, you can always trim the right length. Every comb attachment has its own color that indicates the length. On the front of the hair clippers, you can find which color indicates which length. That way, you can see which comb attachment you need at a glance. You can choose from 11 different length settings between 0.7 to 25mm. Thanks to the 0.7mm minimum shaving length, you can also create short haircuts. You also receive 2 comb attachments to neatly trim the hair around your ears. The blades sharpen themselves, so they always remain sharp and don't need much maintenance. On a full battery, you can use the hair clippers cordlessly for 2 hours. Is it empty? You can also use it corded.
