Seventeen layers. The MoSheng 17x17 condenses what used to be a shelf-sized monster into a 112 mm cube weighing under a kilogram - smaller than previous-generation 15x15s - thanks to 2 mm component walls and a frosted stickerless shell.

Inside, a multi-arm stable core with rounded internal contact surfaces keeps all those layers tracking, adjustable screws tune the tension, and the cube arrives factory-lubricated so it turns acceptably straight out of its window box.

A milestone big cube for collectors who want the summit of the mass-produced world without sacrificing an entire desk to it.

Features:

• 112 mm edge, approximately 975 g
• 2 mm thin components keep it compact
• Multi-arm core, rounded internal contacts
• Adjustable tension, factory lubricated
