I bought these 3-4 years ago, so the expiration date is about 1 year remaining (according to the official website, the expiration date is 5 years). I bought these in preparation for a disaster when my first child was born, and I kept them unopened until my second child weaned. If you are not concerned about the fact that they were stored by an individual and that the children carried the box around saying "What's this?", I hope you will make good use of them.
