The best ink to use for stamps in school uniforms. I tried another kind from a craft shop and it barely lasted. With my daughters old uniform I used to pass them on to a friend for her daughter, and 3 years later any lost items were still being returned to my child because the ink was still there with her name on! It would be amazing if you would sell little bottles with refill ink because it seemed a shame to throw away the one that had dried out, because other than it eventually drying out (which took around 3 years), the ink pad was still in perfect condition.
