Amazon カスタマー 5 I've made a ton of curries using these leaves already and they are perfect for the task. I have no hesitation to recommend this product. They come in a re-sealable bag and should last a few months if kept in the refrigerator. If anything, 100 grams is a great deal of leaves and I will not be able to use them all before they become too stale to use. Other than that, you will not regret getting this product and perhaps you could share them with friends if you feel you have too many of them.
