The Sterile Insulin Pen Needles 31G – 4mm are designed for precise, smooth, and virtually painless insulin delivery using standard insulin pens. Suitable for both adults and children, they offer optimal comfort and safety during daily injection routines.

Manufactured from surgical-grade stainless steel, these needles feature a thin-wall design that enhances insulin flow and reduces injection time. A polymer silicone coating ensures smooth skin penetration, minimizing discomfort and skin trauma.

The ergonomic design allows for vertical, subcutaneous delivery, making them ideal even for patients with limited experience. Each needle is individually sterilized, latex-free, and fully compatible with all major insulin pens on the market.
