Unicorn Horns cartridges are here, helping move tattooing forward. Introducing the first true-to-size needles that match Unicorn needles on bar, eliminating the guesswork in line weight. The boxes and blister packs are easy to read from a distance and come in a simple two-piece slide box for easy opening. The custom body features a raised, heart-shaped washout for a better grip. The exact needle description is printed on the body, not just a number, going the extra mile for convenience. The needle groupings are fitted to each tip, ensuring maximum ink flow with minimal needle movement. The clear, medical-grade long liner tips are slightly frosted to hold ink better and prevent spitting. All mag tips have curved edges to prevent irritation and a foil-type bar to maintain ink flow and keep the needle head down. The rear cap and back stem are electroplated in gold to prevent friction and add a touch of class. They use a medium tension diaphragm, which is believed to works best with the needles. 316L Stainless Steel. 20 Cartridges Per Box.
