Syringe/Needle 1cc B-D Ultra-Fine Short 30g is available in a box of 100 for administering Insulin. This is the thinnest and shortest Insulin syringe/needle that has an 8mm needle length and is called “short”. This is one of the most popular Insulin syringe and needle combinations that so many diabetics prefer because there is less pain from the thin diameter of this needle and it only penetrates deep enough to successfully deliver the Insulin where it needs to be.
