Black, blue, green, red and violet ink pads suitable to fit Trodat Printy 4926 rubber stamps. The pads are supplied as multiple packs of two. In addition to the singular colour pads there is also an option to purchase dual colour red and blue stamp pads, perfect for dating stamps. The ink is manufactured with a water base and contains no toxic substances, no acid, no formaldehyde, and no heavy metals. The ink is hygroscopic, meaning that it self regulates by absorbing the humidity of the surrounding air so that it does not dry out, allowing prolonged usage.
