Due to individual state regulations, some syringe sizes are not able to be shipped to certain states. We recommend 31g, 1cc/1mL/100 unit syringes. If you do not find luck on Amazon, there are distributors such as www.adwdiabetes.com that will ship to every state. Shipping may take longer, but they offer good products at fair prices.
You can also order 29g and 27g needles. These are larger needles but may be available in your state on Amazon with quick shipping.
