McKesson Thin Wall Hypodermic Needles 31G–33G × 1/2 in. are sterile, disposable conventional needles designed for precision injection procedures where a fine-gauge needle is preferred. Available in 31G, 32G, and 33G options, each configuration features a 1/2-inch Thin Wall needle designed to support efficient flow while maintaining a fine external diameter.
Each needle features a Luer Lock hub for secure attachment to compatible syringes, ISO color coding for gauge identification, and protective capsule-style packaging that maintains the sterile product until opened. The compact packaging is designed for convenient integration with Botox injection trays and other precision-injection workflows. These conventional needles are supplied without an integrated safety mechanism and are not made with natural rubber latex.
