The expiration dates for the katakuriko (potato starch) are from 2025/09/11 to 2026/06/02. - Contents: Katakuriko (potato starch) - Number of packages: 40 - These were included in a co-op meal kit for two people to thicken sauces. I didn't use them because I already had potato starch at home. The quantity will gradually increase, but the price is subject to change due to the increase in weight. Thank you for looking.
