Manual Slant Needle 5 Fine is constructed using a needle of diameter of 0.25. A collection of 5 individual 0.25 Fine needles are assembled in a 45 degree angled line to mimic the appearance of blade. The unique design & size can be used for a variety of uses. My favorite purpose for this needle is for patch testing. Every technician should be doing a patch test at least 24 hours ahead of the clients scheduled appointment. You need this time to see how the skin reacts to the pigment or topical anesthetic. Also to determine the choice of color is appropriate selection for the clients skin. For Permanent Makeup and Microblading this needle design is perfect for using in the tiny delicate areas. Lash Enhancements, or individual eyebrow hair strokes beginning in the area by the nose all the way thru to the tail end of the brow. These needles can easily fit into any of our manual handles.
