This stamp will render printed personal information illegible without the clutter and obtrusiveness of a shredder. Using a fast-drying, waterproof, permanent ink, the stamp imprints a block of 385 characters (some of which are askew) in a bold sans-serif font to instantly conceal sensitive information on junk mail, credit card applications, bank statements, and more. The specially patterned impression makes any style of black text indecipherable, even when held up to light. The two included stamps (2 3/4" x 1" and 2 1/2" x 1 1/2") are sized to obscure names, addresses, account numbers in one fell swoop. Inkpads provide up to 1,000 impressions. Includes two inkpad refills. Intended for use on non-glossy, uncoated paper. Set of Two Stamps. (1 1/2 oz.)
