The puzzle is entirely made of aluminium, comprising two main parts, the maze portion and the sleeve portion. The maze is "inscribed" (if this is the appropriate word to use) onto a burnished aluminium tube. The maze does not run the entire length of the tube but rather ends just somewhere before the halfway point. I suppose if the maze did run the entire length, the puzzle would undoubtedly be a lot harder than it is. At the other end of the aluminium tube, a short section of the black sleeve is attached permanently. The second part is the sleeve portion which is entirely in black and holds a small (steel) pin used to navigate the maze. When the puzzle is solved, both parts form nicely into a single black tube. The puzzle is 3 1/2 inches long and has an external tube diameter of 1 3/8 inches.
The puzzle components are overall well made and of high quality. Fit and finish is generally good.....subject to one caveat which I shall elaborate below.

In the process of trying to disassemble the puzzle, at one point I got both the tube and sleeve jammed pretty badly and had to use a certain amount of force to free both parts. While doing so, I heard certain sickening crunching noises as metal rubbed against metal, much like scratching your nails on a blackboard. Thankfully after several attempts over a couple nights, I finally managed to dislodge the sleeve from the maze tube.
Here is where the downside of the puzzle shows itself. Unlike the Removmaze, the pin on the sleeve is not spring loaded. The maze itself also has relatively sharp edges at the bends. As a result moving the pin through the maze is not as smooth or easy as one would have liked. In fact you will hear rough grinding noises from time to time as you twist and turn. Perhaps the tolerances may be too tight, which results in a lack of sufficient "free-play" of the pin within the paths of the maze. One must avoid using any force or the pin will jam as I had experienced. An almost gentle delicate touch is required to push, pull or twist the sleeve through the maze tube to avoid getting stuck and possibly damaging the maze . Handled carefully, the puzzle was problem-free.
Notwithstanding the above, one must remember that this series of puzzles is 30 years old! They were made at a time when technology was not as advanced, unlike today's modern puzzles like the Revomaze which have the benefit of computerised and precision manufacturing techniques.
