The SofTap Genuline 6 regular curved Comfort Pen needle is used for delicately etching individual hair strokes into eyebrows. This technique is sometimes referred to as microstroking, microblading, feathering, embroidery, or microetching. Stretch the skin tight and glide the curved needles across the skin in the eyebrow design to create fine hair-like strokes for a very realistic result. Sterile packaging for one use. After one use needle is disposed of in a Sharp's container for easy and safe cleanup.
