A self-ink stamp is a type of stamp that has an integrated ink pad within the stamping device. This means that there is no need for a separate ink pad as the ink is contained within the stamp itself. To use a self-ink stamp, you simply press down on the stamp and the ink pad will apply the ink to the design or text on the stamp. Self-ink stamps are convenient, mess-free, and easy to use, making them a popular choice for home and office use. They are available in a range of sizes, designs, and colors, and can be easily customized to feature specific designs, logos, or text.
