Product Description
When disassembled and reassembled along the path, the letters do not face each other. While it may appear to be assembled in the same shape as when completed, this is incorrect.
Upon completion, the letters “Key” and “Ring” on the main body should face each other. Inspired by the property called “C-ring parity”—where two C-rings can be assembled in two ways, and once assembled, cannot be switched to the other configuration—this puzzle achieves a “parity change” without disassembly.
Designed by Oskar van Deventer of the Netherlands.
The “Key Ring” letters are designed to read “Key Ring” even when inverted. This is the work of Scott Kim, a genius of inverted lettering.
