ControlFine sterilized pen needles 4mm 33G are designed to make insulin injection fast and painless. The minimum length of 4mm reduces the chance of intramuscular injection and the fineness of 33G guarantees a smooth injection.

STERILIZED-SINGLE USE ONLY

USEFUL TIPS: ControlFine sterilized pen needles are strictly for single use. After the first use the pen needle is no longer sterile and has cell and tissue residue left on it. Reusing it can cause pain, injury or infection of the subcutaneous tissue. Disinfection of the pierced area and disposal of the needle after the use is strongly recommended. Consult your physician for the recommended piercing angle.
