I have viewed items similar to this Black Out Stamp in other forms but never considered purchasing due to the "cheesy-ness" factor. Kes'pon Plus' Black Out Stamp is well made and will black out personal information on mail envelopes, magazines, and catalogues. However, even when the ink dries, I can take my thumb and rub the ink off the page, clearly revealing my information underneath the ink. This is where the item is slightly misleading. Yes it will black out information which requires protection for documents, however do not expect the black out to be permanent. It will not adhere to glossy printed paper.
