Hand tool set designed for setting 11 mm (3/8 in) grommets cleanly through fabric and craft substrates. Use with compatible grommets to add reinforced openings on curtains, bags, aprons, and organizers. Compact and workshop-friendly, it delivers repeatable results when used on a firm surface with a protective scrap. A practical addition to hardware kits for sewists who want sturdy, professional eyelets without investing in a press for occasional home or small-studio projects.
