Recommended by law enforcement and insurance companies as an effective theft prevention and recovery measure, permanently identifying your valuable property is now as easy as using a pen. Engrave your name, initials, address, phone number or any other important information on tools, personal electronic devices, computers, jewelry, professional equipment, family heirlooms, bikes and golf clubs. Thieves prefer to steal and sell items with no permanent ID, but if your property is stolen your personal engraved information makes it easier to recover. One-year warranty and Jack's Tool Shed worry-free Satisfaction Guarantee.
