These Trodat robust metalic  date stamps comprise of a number of rubber bands which need to be altered to give the correct date. The actual date height depends on the product chosen. Most customers choose 4mm as a 3mm date is difficult to read - We very rarely get orders for the smaller 3mm date stamp. We manufacture a natural rubber die using your choice of text that surrounds the date itself. Care needs to be taken while altering the date on the bands to prevent damage. We are usually able to replace damaged bands at cost but it is often easier to replace the stamp, particularly if the stamp is old.  You will need an ink pad for these stamps. Various ink colours are available - black, (sometimes red) is the most popular choice.  The ink pad will need replenishing from time to time - ink is available from us.
