Built-in ink pad: The stamp contains an internal pad that supplies ink to the rubber die.
Automatic inking mechanism: When you press down, the rubber surface rotates or flips to make contact with the paper, then returns to the ink pad.
Consistent impressions: Each stamp produces uniform, clear prints with minimal effort.
Replaceable ink pad: Many models allow you to swap or refill the ink pad when it dries out.
Durable casing: Usually made of plastic or metal to protect the internal mechanism.
