The sakura is a perfect representation of Japan and it is a ZIREL puzzle that truly tests the patience of those that attempt to solve it. Every single piece is unique to its own visually and has indications of what it is supposed to be connected to. There are many pieces that look very similar as well to add to the challenge of solving it. Notably, all of the pieces are made from metal and it comes together to create a Sakura or Ume in a stainless steel mirrored finish.
