Puzzle Details
From Calvin's HKNowStore:
"Dia-in-Dia Octahedron Black Body (Ji mod)
This is a hand-made Diamond-in-Diamond Octahedron puzzle by my friend, Ji. The puzzle design is beautiful and with very nice stickers. The puzzle consist of a 3x3x3 cube as the core parts, and 3-D printing outer parts. The turning is smooth. It is good for collection and also challenged to solve."
In fact the turning is not as smooth as described and needs careful adjustment.
Size: Edge length 120mm, height 97,5mm
