Aiguilles Hypodermic Needles The tin case houses a full set of twelve hypodermic needles, each securely held in place and covered with a clear plastic wrap. The case’s lid bears an inscription in blue ink: “Aiguilles Hypodermiques Acier Inoxydable Stainless Steel Medinox Made in Switzerland Hypodermic Needles.” This is accompanied by “1DZ” on one bottom corner and a black stamp “12.” Inside the box, a metal tray features the holders where the needles are secured in the slot. These needles were designed to be a push-fit for the original Record syringes. Each needle is engraved with the number 12 at the end that fits into the syringe. The set is completed with a bundle of cleaning wires. Hypodermic needles are used to either inject fluids into the body or withdraw them, and these particular needles were specifically designed for the original Record syringes, patented by Dewitt & Hertz. 1925-1975
