A hard, blue artificial flower. Its petals shall never wither, nor shall its colors fade.
An ominous pinion with edges of unsurpassed keenness. Perhaps it represents an unnaturally uninhibited nature.
A pocket watch with a cover that cannot be opened. Yet it ticks and tocks away, following the inexorable flow of time.
An intricately-made cup. Its appearance betrays nothing of its age to an observer.
A mask that covers the face, hiding one's expression from others.
