With a polished nickel frame and a bold dark inlay, the Black Series Square Engraved Keychain offers modern contrast in a compact shape. Unlike similar designs found elsewhere, our version features a solid nickel back that can also be engraved — creating a tone-on-tone effect on one side and a crisp light-on-dark effect on the other. The result is a keychain that feels substantial, balanced, and thoughtfully designed. Front-side laser engraving is included in the price with no setup fee, and back engraving is available for an additional per-piece charge and a one-time setup fee. The engraving area measures 1" x 1", ideal for logos, initials, or short text. Each keychain measures 1.375" wide by 2.75" high and includes a sturdy split-ring attachment. Every piece is packaged in a two-piece gift box, giving it an upscale presentation. The minimum order is 50 units with a standard 5-business-day production time. All orders include a digital proof before production. We engrave and stock in-house, ensuring consistent quality, savings, fast turnaround, and clear communication throughout the order process.
