DESIGNER: Ishino Keiichiro; Original design by Koji Kitajima MATERIAL: Sapele or Figured Maple RELEASE DATE: 2023.08.29 EDITION: 41 Total Copies Made SIZE: 2.625" 6+6=CUBE Improved is a design dating back to 2007, Ishino's improvement of an original design 6+6=CUBE by Koji Kitajima. Twelve total pieces interlock to form either two solid notchable six-piece burrs or one twelve-piece cube. We had seen a copy of the original design by Koji Kitajima and produced by the Hikimi company from Japan on the Marketplace, and we thought it would be a great design to make available. The improved version features a cube with 2 assemblies containing no visible notches on the exterior faces. 41 total copies are available for this release, each signed and dated. 6+6=CUBE Improved ships in the disassembled configuration.
