New from Noris, #007 is a non-hazardous ink that is specially formulated to mark on nearly any surface. Designed for use in self-inking stamps for use on the widest range of surfaces including polished metal, coated and uncoated paper (glossy paper), PVC, Polypropylene, Wood, Ceramics and Glass. Extended usability ink remains wet in the ink pad for longer ideal for use in self-inking stamps. When using Noris #007 Ink, there are some important things to note: Once the ink dries out, certain components remain in the pad, including binding agents and other ingredients. Adding more ink will just cause these to build up and harden over time. To prevent this issue, Noris has developed an effective solution in the form of an ink refresher. When the pad becomes dry or is already dry, it is recommended to use the refresher before re-inking. Simply apply a few drops of the refresher onto the pad and gently rub it in using a small stick. You can find the refresher here: Noris #007 Refresher Please note that over time, the clarity of the imprint may diminish since the refresher does not contain dyestuff or pigment for colour enhancement. In such cases, it is advisable to switch back to using regular ink for re-inking. This process can then be repeated as needed. We highly recommend using the refresher regularly to maintain the fluidity of the ink. This can also revive a dry and unusable pad, particularly if you use the stamp infrequently. In cases where you do not have the refresher on hand, it is advisable to have a spare dry pad as a contingency plan for those occasions when you need to complete tasks and the original pad becomes ineffective.
