Just press and print! It's that simple with PSI and iStamp pre-inked rubber stamps. You don't need a separate stamp pad because the ink is in the rubber stamp. You'll get clean, crisp impressions every time you use your PSI pre-inked rubber stamp, and after thousands of impressions just re-ink your stamp with PSI oil based ink for thousands more! LOGOS can easily be incorporated on your stamp - Image files can be uploaded on the stamp customisation page, and as our pre-inked stamps give a quality impression we require high resolution files. eps, ai or pdf files are preferred with all fonts outlined (jpeg and png files are not suitable). Details of where you would like the logo placed can be added in the comments section of the order form.
