Using these sterilizing storage pouches is easy. First, make sure your tools and implements are properly disinfected. Then, place them inside the pouch. Seal the pouch using the self - sealing feature. Store the sealed pouches in a clean and dry place. When it comes to maintenance, keep the pouches away from sharp objects to avoid punctures. Also, check the expiration date on the box, as expired pouches may not provide effective sterilization. If you notice any damage to the pouches, do not use them and replace them with new ones.
