The new and improved Unifine Pentips Insulin Pen Needles 32G 4mm are designed to provide the most comfortable insulin injection. The triple sharpened needles are ultra-thin and developed with anti-coring technology for easy insulin delivery. These needles for insulin pens come lubricated with advanced silicone to help with easier penetration, and provides more glide force. These insulin needles are compatible with all the insulin pens currently available in Canada. Considering the risk of latex hypersensitivity reactions, especially in children with diabetes, each insulin needle is completely latex-free, reducing the risk of latex allergic reaction. These needles meet user expectations for a more comfortable injection. After injecting, the needle should be removed and a new needle inserted for the next injection. Repeated use of the same needle can cause the feeling pain at the puncture site, infections, destruction of the epidermis (lypohypertrophy) and blocking of insulin flow.LATEX FREE PENTIPS: These diabetic needles are completely rubber latex free and easy to twist on and off the insulin pen. Injecting with a triple bevel sharpened ultra-fine 4mm insulin needle may lower anxiety during injecting, as it is far more comfortable. UNIFINE INSULIN NEEDLES 32G 4MM: These needles for insulin pens use the latest technology, ensuring the excellence of the final product. The unique needle design reduces the risk of needle breakage or bending. These needles are fully disposable. UIVERSAL FIT: Compatible with all major diabetes medication pens.
