they usually come with the attachments as well. If i were you, I would invest in some good thinning shears as well. Good clippers, good scissors, and good thinning shears and you will be all set
I have been cutting my cockers hair for several years and have always had good scissors but only 1.5 years ago got good clippers. it made ALL the difference in the world. They cut through her hair like a hot knife in butter. It was such a relief. Next time I will be sure and get some that don't get so hot. these got really hot!!
