Karen's new favourite needle! This 1 micro is a single needle cartridge. It has a long taper, which means it implants pigment far more finely. With good technique, this needle can deliver super-fine hair strokes. The reduced surface area of the needle point also means that this cartridge can be used as a suitable alternative to the 1 liner when working on fragile skin. Warning: This is a super-fine needle and must be used with care and extremely light to prevent implanting pigment too deeply into the skin. Advanced brows training or experience advised.
