The WellFine Insulin Pen Needles (4mm) are premium, medical-grade needles designed for the comfortable and precise delivery of insulin. Manufactured in South Korea using advanced thin-wall technology, these needles are engineered to provide a nearly painless injection experience while ensuring maximum safety and compatibility.

Key Features & Benefits

• Ultra-Thin Wall Technology: The 32G extra-thin wall design allows for a higher flow rate of insulin with less injection force, making the process smoother and faster.

• 4mm "Short" Needle: The 4mm length is the clinically recommended standard for all body types. It ensures the insulin is delivered into the subcutaneous fat layer and reduces the risk of painful intramuscular injections.

• Triple-Bevel Precision: Each needle tip is precision-ground with three facets to create a sharper point that glides into the skin with minimal resistance.

• Medical-Grade Silicone Coating: A special lubricant coating reduces friction during insertion and withdrawal, significantly enhancing user comfort.

• Universal Compatibility: These needles are designed to fit all major insulin pens available on the market, including those from Novo Nordisk, Eli Lilly, and Sanofi.

• Non-Toxic & Pyrogen-Free: Produced under strict quality control in Korea, ensuring the needles are sterile, safe, and free from harmful impurities.

How to Use Safely

1. Prepare: Wash your hands and clean the injection site.

2. Attach: Remove the paper tab from the needle and screw the needle straight onto the insulin pen until tight.

3. Prime: Remove the outer and inner needle caps. Perform a "safety test" (prime the pen) to ensure insulin is flowing.

4. Inject: Hold the pen at a 90-degree angle and insert the needle. Press the dose button and hold for 6–10 seconds.

5. Dispose: Replace the outer cap, unscrew the needle, and dispose of it immediately in a sharps container.

Storage & Safety Guidelines

• Single-Use Only: Always use a new needle for every injection. Reusing needles can cause blunting, pain, and skin lipohypertrophy (lumps).

• Check the Seal: Do not use if the protective tab is broken or damaged.

• Keep Cool & Dry: Store at room temperature in a dry place away from direct sunlight.
