WellFine 32G injection needles are designed for use with insulin pen injectors. These needles feature a thin-walled technology that allows for a smaller outer diameter while maintaining the same internal diameter, resulting in a more comfortable injection experience.
The 4 mm length and 0.23 mm diameter provide a balanced design for effective and less painful administration. These needles are manufactured in South Korea and come in a pack of 100, ensuring convenience and reliability for regular use.
