Superior durability with thick wall cannula and plated brass hubs reduce breakage six-fold over conventional needles. 100% detectable in metal detection systems against only 15% for standard needles. Precision ground tip stays sharper longer, allowing for multiple injections without burring. Gauge stamped on hub and packed in red cartridges and boxes for easy identification. Cartridges are tamper evident and labelled with needle size and lot number.
