Pre-inked round stamp with a short handle is perfect for inspection stamping. The laser-engraved rubber makes this stamp strong and durable for many years of use. Stamp makes approximately 50,000 impressions before needing to be re-inked. Impression size is 3/4" in diameter. Use Xstamper Refill Ink only. Use of any other ink will void the warranty. Re-inking is easy. Simply pull off the handle (top) and place two to three drops of ink into the opening (center) of the mount.
