This Gold/Silver Metallic Stamp Pad features high-quality pigment ink that provides vivid coloring with minimal bleeding, ensuring sharp and vibrant impressions. The ink is acid-free, water-resistant, and light-resistant, making it ideal for long-lasting, archival-quality prints. One of the standout features of this pad is that it remains moist even with the lid open, so you don't have to worry about the ink drying out. It delivers clear and crisp impressions, even on dark-colored paper, without showing through. However, it is not suitable for non-absorbent surfaces, art paper, coated paper, or any other materials that don't absorb ink well. If needed, ink on the print surface can be easily wiped off with a tissue paper moistened with water. For refills, be sure to use the gold (part number: SPM-15-GO) or silver (part number: SPM-15-S) ink designed specifically for this metallic stamp pad.
