    Nice and small and easy to use

    Posted by Stephenie Roth on Jan 15th 2020

    These are working great for my small dog. They are smaller in gage and needle size than what was originally given to me by my vet and she seems more comfortable with these. Also makes me more comfortable. I love that there are half markings.

    .3cc 31G syringes

    Posted by Ashley Calloway on Oct 2nd 2019

    I rarely give a five star review. However, these needles are so fine and so sharp that even after going through a rubber plunger on a vile, it maintains that sharpness. My dog Bandit did not feel the stick at all. I had been using a 29G needle, not only is it slightly larger but the needle itself is longer. With the .3cc 31G syringe it’s a shorter needle so there’s less risk of going to deep Or going through the other side of the skin.
