The Caja Metálica de Estaño first appears in Volume 2 as a modest, silver-plated rectangular tin whose unassuming weight and Spartan carvings belie its role as a sealed vessel for dangerous or forbidden knowledge. Across the series it evolves from a simple container into a recurring motif of hidden truths and suppressed memories, its very plainness becoming a narrative device that signals the presence of sealed fates or forgotten identities. By later volumes, the tin’s significance expands beyond its physical form, symbolizing the tension between concealment and revelation that drives the overarching mystery.
