The Andis 21318 four-piece comb set adds selectable guide lengths to a compatible detachable-blade clipper. It includes 1/8, 1/4, 3/8 and 1/2 inch combs, allowing the groomer to choose a guide for bulk removal, tidying and finishing work.

A metal clip secures each comb over the blade. The snap-on fitting makes it straightforward to exchange guides when another section needs a different comb size. Andis's product specifications identify a Size 10 blade as the fitting requirement, so check both the blade and clipper before selecting the set.

Compatible models include the Andis AG, AGC, AGP, AGRC, AGCL, AGR+, AGRV, MBG and SMC families. All four listed comb sizes are supplied in the set, providing a compact group of guide options for routine grooming.
