Effective Privacy Protection: Security roller stamp features a special letter design that prints over confidential information, making personal details unreadable. Ideal for covering sensitive documents such as bills, bank statements, medical records, and prescription labels. Wide Coverage Design: The 20mm wide roller efficiently covers large areas of private information in a single stroke, eliminating the need for multiple passes. Unlimited Re-inking: Ink can be refilled when depleted using standard stamp ink (sold separately). Add approximately 2 drops at a time for optimal performance. Time Saving: Works smoothly on standard paper, envelopes, and package labels. Quickly obscures information without the need for a shredder. Notice: Actual color may vary slightly due to differences in monitor displays and lighting conditions. Slight measurement deviations of 1–3 cm may occur due to manual measurement processes. Asian sizing may run smaller than EU/US/UK sizes; please refer to the detailed dimensions before purchasing.
