Bizstory MapMark II — Eiffel Tower Enamel Keychain

The Bizstory MapMark II Eiffel Tower Enamel Keychain brings the romance of Parisian architecture to your everyday carry with remarkable miniature precision. The zinc alloy base plate measures 35 mm by 60 mm and is stamped at 2.8 mm depth to replicate the iconic lattice ironwork of the original 1889 tower structure. Hard enamel filling is applied through a seven-step process: base color pour, kiln firing at 820 degrees Celsius, surface grinding to 0.3 mm flatness tolerance, and two-coat clear lacquer seal. The result is a glass-smooth color field with a Mohs hardness of 5.5, resistant to scratching from keys and coins during daily bag carry. The alloy body receives an antique bronze electroplate at 1.5 micron thickness to accentuate the architectural relief detail across the tower frame. A lobster claw clasp in 304 stainless steel provides a secure, tool-free attachment to any keyring, bag zipper, or lanyard loop with a gate opening of 7 mm. The enamel palette includes midnight blue, champagne gold, and Parisian rose variants. Each unit passes a 48-hour salt spray test confirming corrosion resistance equivalent to ISO 9227 standard. Net weight is 22 g. Packaged in a kraft paper gift sleeve, making it ready for gifting without additional wrapping.
