I have many other puzzles, but here are my twisty puzzles:
The first mass produced bandaged 3x3x3.
6X6X6 & UP
The first mass produced 6x6x6. A six layered cube.
The first 7x7x7. A seven layered cube.
Meffert's six colour 1982 version. Roughly 31 mm along an edge.
HEADS & OBJECTS
A sliding blocks puzzle with only edges and corners.
Probably the most popular tile sliding puzzle ever.

This 3x6 Whip-It stands approximately 7 mm tall. Produced in Macau. Original LJN Whip-Its were made in Hong Kong.
