NovoFine 31G 0.25×6 mm pen needles are ultra-thin, single-use needles designed for comfortable and precise insulin delivery. With a 31-gauge thickness (approximately 0.25 mm) and a 6 mm length, these needles are suitable for subcutaneous injections, minimizing the risk of intramuscular penetration. They are compatible with most insulin pens, including models from Novo Nordisk, and feature a unique design to reduce the risk of needle bending or breaking.
