Cobble Hedge (Pento Hex) was kunio Saeki's exchange puzzle for IPP16 in Luxemburg, 1996.
Kunio Saeki was president of Toyo Glass.
The puzzle consistsof a cylindrical glass that holds 10 x 5 glass marbles in specific color patterns.
A plastic cylinder ensures that all marbles touch the cylindrical part of the glass.
The puzzle goal is to arrange the marbles so that each line of 5 marbles contains 3 marbles of the same color, and no marble touches a marble of the same color in an adjacent line.
This is a relatively heavy puzzle (540 g), packed in a box measuring 9 x 8 x 8 cm.
