These darling personalized stamps are the perfect way to address an envelope or create note cards and stationery that is totally your own. These stamps don’t require extra ink cartridges because the stamps are made differently with different kinds of inks, and therefore get 30,000 impressions.  They simply won’t run out of ink!  Therefore, you don’t have to buy additional inks…PJ’s ink is oil based, which is cool because unlike water based ink they will never dry up.
