The Philips Grooming Kit QG3320 features a full size trimmer that ensures pleasant and friction-less shaving sessions. This full size trimmer allows you to maintain your style get clean and sharp lines around edges or create perfect stubble. It is for neck line, sideburns and chin. The steel blades lightly brush against each other, so they sharpen themselves as you trim. The blades stay extra-sharp to always cut hairs neatly and effectively, but have rounded blade tips and combs to prevent skin irritation.
