Newest samples, acquired in October. One packet is enough for 3-5 uses, so 3 packets are enough for you to try. No need to comment before purchasing, please buy directly. ⚠ It seems there are people who ship this product without any packaging, directly in an envelope! As common sense (manners), I will not do that. I will put it in a new OPP bag and then ship it in an envelope, so please rest assured. Available in stock, can add more. Yu-Yu Mercari mail shipping +120 yen. Please take a look at my profile for bulk purchase requests and transactions.
