Does the magnetic Acuclip help maintain sterility of the needles after opening?

The “magnetic” nature of the clip does not affect or enhance sterility itself. The fact that the magnetic clip tightly holds the shafts of the needles between the top and bottom layer of the pouch conveniently reduces airflow and possible contamination of the shafts of the needle. The net effect is that the shafts of the needles remain in a clean field for a longer time than other packaging methods.
