how can i know if this is sterile? the blue external and internal mark dark brown/dar grey? initial pink is same?
4465 Dynarex Self Seal Sterilization Pouch 7½In X 13In 200/Box, 5 Boxes/Case
when i sterilized the pouches on the left upper corner-the initial blue external and internal dots marked dark brown/dark grey, but in the upper right corner the initial pink stays pink (external and internal) that's correct?
