  • I appreciate the packaging…
Size: 1/2cc-31G 5/16" Number of Items: 20
I’ve had so many “fragile” packages come without proper padding/protection and BROKEN upon arrival that I’ve been hesitant to order anything remotely breakable online. I took a chance with these. They came properly secured, and not a single syringe was damaged. The needles themselves were thin and painless upon insertion. I use this particular size to self-administer B-12 injections (3x weekly) and they work perfectly. ... show more

  • Would recommend
Size: 1/2cc-31G 5/16" Number of Items: 20
I was scared I was going to end up with a needle that hurt. I honestly didn’t feel any pain with these so I would definitely recommend. Will be buying these from now on.

  • Do Not Buy
Size: 1/2cc-31G 5/16" Number of Items: 20
I’m brand new to the whole needle game so I figured a needle is a needle? I was so wrong. These are pure garbage. They’re dull and hurt going in and also coming out. They bend so easily and if they don’t break off in the vial then you still have to deal with it being difficult to draw anything out. Just spend the extra couple of bucks and get the ones that are highly rated by people who know their stuff. ... show more

  • Softest subcutaneous needle
Size: 1/2cc-31G 5/16" Number of Items: 20
The tip of this needle goes in sooo gentle you barely feel it! It is a short tip as well so it goes in with ease! Tried several needles before this one and this is by far the best! Buy This One! You Will Not Be Disappointed!

  • Worked great for me
Size: 1/2cc-31G 5/16" Number of Items: 20
I was worried that, based on some reviews, these would be dull. That wasn't the case for me (or at least, I didn't notice). They were the same as what I received from professional offices. Cheaper and more convenient.
