We have designed and created our disposable microblading pens for brow artists who are both just beginning their career, and for advanced artists who like working with very fine, precise blades. We believe all microblading tools should be disposable, eliminating the risk of cross-contamination. Our nano pens are .18mm 306 medical-grade steel. All of our other pens are .20mm 306 medical-grade steel. Your clients will love the hairlike strokes these blades provide.
