The Gem 9 Cube is the last member of the first-batch Gem series. This one is features a void mechanism that is different from the other 9 types. However, this void mechanism is very tight and hard to turn. Before turning, you have to align the grooves.
This one is highly collectiable puzzle. It is not designed for speed cubing or for an easy-turning solve. For collection purposes, this is good to have in order to complete the Gem series.
Includes an extra set of stickers.
