Artline Stamp Pad Refill Ink (ESA-2N) is a refill product containing 50ml of red ink. This imported product is manufactured in Malaysia. When the ink in your existing stamp pad fades, you can gently press the side of the bottle to inject it evenly onto the pad surface for reuse. It is an essential consumable for environments where stamps are frequently used, such as offices and public institutions, helping to extend the life of stamp pads and maintain clear impressions.
