Pre-inked round date stamp with a long handle is great for postal use. It comes with a 10-year date kit so you can change the dates with your tweezers. 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 1-3/16" in diameter. Use Xstamper Refill Ink only. Use of any other ink will void the warranty. Re-inking is easy. Remove the handle (top) from the stamp and place three to four drops of ink into the opening of the stamp. When you contact customer service to customize your stamp, specify whether you prefer the date in vertical or horizontal date format.
