Self-inking stamps are stamps that have an internal ink pad that automatically re-inks the stamp after each impression. These stamps are very convenient as they do not require a separate ink pad and the user does not have to manually re-ink the stamp after each impression.

Self-inking stamps come in various sizes and shapes and can be customized with text, logos, or designs to fit specific needs. They are commonly used for personal and professional purposes, such as endorsing documents, marking packages, and creating custom messages.

To use a self-inking stamp, simply press the stamp down onto the desired surface and the ink pad inside the stamp will automatically apply ink to the design or text. After use, the stamp will retract back into its housing, ready for the next use.

To replace the ink pad in a self-inking stamp, the user typically needs to remove the old pad and insert a new one into the designated compartment in the stamp. The frequency of ink pad replacement depends on the usage of the stamp and the quality of the ink pad.
