Purchased in October 2024, I didn't produce much breast milk, so I only used 5. One bag out of the two in the box was opened, and 5 were used, leaving 20. The other bag remains unopened and stored. A total of 45 bags remain. A date label will also be included. Breast milk storage bags for freezing and refrigeration, 50 bags per pack, 40ml capacity each. - Brand: Pigeon - Capacity: 40ml - Quantity: 50 bags - Use: For freezing and refrigeration Thank you for looking.
