The AlCyl (I didn't know what "AlCyl" meant), but I was informed by 4 very experienced puzzlers (see below comments), 3 of whom are also well-known puzzle bloggers; Oli, Allard and Kevin, that it's a combination of Aluminium + Cylinder = AlCyl, thanks guys... gosh I am dense! It was designed by Hirokazu Iwasawa, who also gave us the triangular-shaped Tritalon, which was reviewed earlier in this blog.
The puzzle measures about 6cm tall and 4.8cm across in diameter. It is made of aluminium and anodised blue and looks very much like a Revomaze Blue Extreme with the ends lopped off. Construction, fit and finish of the AlCyl is very good and the puzzle feels solid.

However do be gentle if you are going to open and close the AlCyl often... assuming you are going to use it as a repository for things. Its tough looking exterior does belie its slightly more delicate interior construction.
From a puzzling perspective, the AlCyl may not really be value for money; but well worth the price if you are looking for a rare, hard to find and high quality collector's item.
