Wahl’s Stainless-Steel Attachment Guide Combs glide through all animal coat types. The attachment guide combs provide 8 additional cut lengths that let you keep up to 1 inch of hair. Attachment guide combs are color-coded for easy reference and are available either individually or in one convenient 8-piece kit. For best results, use attachment guide combs with Wahl 5-in-1 blades.
