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, those with recurring purchases, and previous purchasers who are followers receive individual pricing. Motota-kan's unique point discounts are available. If you contact us at the time of purchase, the point discount will be applied. Also, service items (auxiliary devices, screws, etc.) will be included.
