Answer: In instructions they mentioned that Contents should be used within 3 weeks after opening or till expiry date. I used nan pro 1 for my baby. I have bm but not too much. So i used nan twice in a week if he required. Actually now its completed more than 1month after opening.Till now there no problem. Note that we should keep it airtight container.
