The Golden Eggs (they are usally all called "Golden", although having diffent colours) are produced by Uwe Meffert based on a concept by Tony Fisher.
Currently available are the colours:
gold, silver, white, red, green, blue, yellow.
Because the puzzle is based on a standard Skewb mechanism, it is quite large.
Top-to-bottom height is about 11cm, diameter around 8cm.
The puzzle comes with a stand with the imprinted name of the Orbix puzzle.
The quality of the puzzle is quite good, although pieces may pop from time to time, because the mechanism seems to be a little bit to loose.
