After several years from manufacture, even unused carbon becomes old, and its lifespan (expiration date) expires, rendering it ineffective. The older the carbon, the less effective it becomes. Beware of fakes and old carbon. Many places openly sell fakes as genuine products. Regular customers, subscribers, and previous purchasers who are followers receive individual pricing. Genta-kan's unique point discounts are available. If you contact us at the time of purchase, point discounts will be applied. Alternatively, we offer service items (auxiliary devices, screws, etc.). Regular customers and subscribers are given priority. Followers who have unfollowed us are excluded from discounts. #KoukenCarbon #KoukenTo [Important] Carbon has a lifespan (expiration date).
