I've long questioned the wisdom of calling this series the 'Ninja' series. Apparently, the story behind it is that someone's son was watching, get this, Teenage Mutant Ninja Turtles cartoons (realizing that they must have been dubbed into Italian makes it even funnier) and, based on that, and the faux tortoise shell style acrylic stem, they decided it would be a good name. It's a little tortured and contrived, but it does make some perverse sense.
Regardless, don't let the naming silliness sway you. It's a lovely pipe-- the combination of the medium brown/tan two-tone stain on the sandblast is lovely, as is the boxwood ring on the stem and the smoky, amber-hued acrylic stem that completes the composition extremely well.
