Insulin Syringes 31G, 0.5 mL (100-count)

The workhorse: a very thin 31-gauge needle on a barrel marked in units (0 to 50).

• 31G
• U-100
• 0.5 mL
• 0–50 units

Why you’d want it: The most popular all-around size for small, precise doses. Start here.

Picking tip: Confirm the listing says U-100 and that syringes come individually wrapped, not loose in a bag. Barrel colour is cosmetic — brands use it to tell their own sizes apart, so match the numbers, not the colour.
