The Caja de Cartón con Algodón first appears in Volume 2 as a seemingly mundane brown cardboard box lined with thick white cotton padding. Across the series, this ordinary container evolves into a vessel of profound significance, its padded interior becoming the resting place for artifacts of immense power and mystery. What begins as a simple shipping box transforms into a symbol of containment and preservation, its cotton lining serving as both cradle and shroud for items that could reshape the world of mysticism.
