The TERUMO Spinal Needle tip is beveled for smoother penetration. However, it has just the right amount of penetration resistance to give you a fingertip feeling of exactly where the needle point is. The blister pack's peel-apart feature allows you to dispense the needle into a sterile field, and the protector keeps it sterile until the very moment of use. Color-coding is used on the stylet-hub, blister pack, and shelf package for rapid gauge identification at every stage.
