Protect your identity and personal information from theft and fraud with an ID blocker stamp. As rollers that coat any amount of text with oil-based ink, these Guard Your ID stamps make all obscured information unreadable. In response, shredding documents is no longer the sole protective mechanism against identity theft, and for comprehensive security, the ID stamp can be rolled on uneven surfaces, from junk mail to canceled checks. Although ink is used, the stamp is environmentally friendly.
