All expiration dates are May 1, 2026. These were purchased in the United States. They are liquid milk. If you buy several, you don't have to buy 10; you can buy less. They are also sold on iHerb and Q10, so if you want to see the Japanese translation, please check them out. They are very convenient for nighttime feedings and when you're out and about. There's no need to warm them up. Perfect for babies with sensitive stomachs or those who have gas. #liquidmilk #formula #baby
