0.5ml Syringes 31G 1/4 Inch

Extra tiny needle and syringe. 29G is on the small end of needle sizes. 29G needle outer diameter 0.33 mm (0.01325 inches), inner diameter 0.184 mm (0.00725 inches) I'm very confused as to the intended use. The listing clearly states: "Not for professional medical use, only for scientific laboratories, industrial and household tasks" and "Sterility Rating: Non-Sterile" yet the individual plastic package says "Sterile" " Sterilized by E.O. Gas" "Disposable Insulin Syringe". The syringe has "Single use U-100 Insulin" stamped on it. Without the listing these appear to be appropriate for injections on humans. However, I'm not injecting myself on anyone else with these and plan to only use them for dispensing tasks. They are easy to control to produce a small drop and place it accurately. The plunger glides in the cylinder with very little stick/slip friction effect. I wondered if they are lubricated but the plunger cannot be removed from the cylinder for inspection. My photo shows drops placed location control and size control. I was even able to "vacuum" up misplaced drops or over size ones. For max control be sure to tap out all the air in the syringe before making the droplets. I plan to use these for bonding rhinestones on clothing, purses or other items for decorative effect. I think they will work great.

Everyone of these of individually packed syringes worked perfectly. Needle size is ideal for small veins. Painless and easy to use. Invaluable for smaller veins.

Needle bends easily, not a good choice if you are just starting to use insulin, It took me 3 syringes before it didnt bend. I have a hard time holding the bottle still while removing the liquid.

These are great injection tools that I'll never get enough of. Let's get into it. I had no trouble with smoothness or resistance while drawing for my vitamin injections. The vacuum is optimal, and the plunger is extremely precise. There were no leaks either. I got my measurements right on the money, and the syringe doesn't feel cheap. The plastic is sturdy and not needlessly thick. It feels nice and standard. The tube doesn't bend, and the needle didn't either. I hit the mark, got no play, and it slid right out the same way it went in. I barely felt a thing. A bee sting would be an overstatement. It was more like a mosquito bite for me. As expected, these are high quality insulin needles that can be used for other prescribed injections. No problems to report! These are excellent value for the money, and highly recommended!

I’ve been using these 31g syringes for a few months now and they’ve consistently delivered excellent results. The ultra-fine needle makes injections nearly painless—especially important if you’re doing daily injections like insulin or other subcutaneous medications. Pros: Extremely fine needle: Minimal discomfort, even for sensitive areas. Smooth plunger action: Doesn’t stick or jump, which is crucial for precision. Clear, easy-to-read markings: Great for accurate dosing. Individually wrapped and sterile: I appreciate the hygiene and peace of mind. Cons: Not ideal for drawing up thick liquids—understandable for a 31g needle. The barrel size is on the small side, so it’s best for small-dose medications. Overall, if you're looking for a reliable, comfortable syringe for low-volume, subcutaneous injections, this is a great choice. Just make sure it's appropriate for your medication and volume needs. Would definitely repurchase!

These are perfect for measuring very exact small amounts. They are not sold for medical only lab use. They aren't really made to pop blisters etc etc. For painting crafts and detail work, these are way more useful. The clear markings make it easy to dispense tiny, repeatable amounts of paint or ink, which is great for dot art, miniatures, or touch-ups without turning your project into a puddle. They also shine for precision glue work, letting you put a small drop exactly where you want it instead of everywhere else. Simple tool, big control, and far less cleanup when things inevitably go sideways. Good value for the money and no one looks at you strange for buying them.

Well packaged. The plunger works smoothly and needles go through skin smoothly, no bending.

Would’ve preferred a smaller gauge needle. Used for GLP 1 compounded medication.
