 This tutorial is to refill the non-refillable roller stamps made by PlusGuard your ID. It is not for the refillable roller stamps like this. This stamp has a removable cartridge. The cartridge is not refillable and will cost $8. We cut the stamp core open. You can see there is a sponge cylinder. A layer of rubber covers the sponge. To refill, we remove the roller's cover first. There are two methods. First, the rod comes off in two pieces. You can pull out the part with a more extended rod and fill in space with ink and leave it for 24-48 hours. Then there is another way. We used a rotary tool to drill two holes through the sponge. Then we fill it up with ink, using the precision tip. Now we can use the roller stamp right away. It will take about three to six hours for the ink to spread but you don't have to wait for it.
