SECONDS: The Aeternus AenigmaSECONDS: This new and improved colour changing puzzle delivers the same unique magic you expect. The only difference is that the packaging may be imperfect or may come in a different style. Unlike traditional puzzles with a single colour state, the Aeternus Aenigma features four distinct colour states that shift depending on the viewing angle. You will enjoy the same mesmerising experience at an even better price.
