Replacement cartridges built for Hydra Pen H3 and H5, featuring serum-channel needle design that draws serum from the reservoir through the needles during treatment. Available in needle and nano options to match different sensitivity levels. Each cartridge is sealed and sterilized for single use. Using genuine Hydra Pen cartridges preserves the serum-flow mechanism that third-party cartridges often block. Free shipping across Canada.
