Every stamp becomes valid. Unclean stamps are widespread. A poor or old ink pad does not cover the stamp with the right amount of ink, making some stamps hard to read. A low-quality new stamp cartridge covers the entire stamp, including the gaps in the stamp design, with ink. The result is a thick blot on the document. Imagine placing a final stamp on a really important document with a hologram and other details to enhance its validity. The document must not be ruined by an opaque stamp or a solid ink blot. How can such a scenario be avoided? Simply use a high-quality stamp and a stamp refill pad. This refill pad for Colop P20, L20, and S20 is made from high-quality materials specifically chosen for this purpose.
