Where to buy Tucano 12" PB

Does anyone know if and where I can still buy a Tucano second skin element sleeve for the 12" powerbook? I remember seeing them a couple years ago and loved them, but didnt have a 12" at the time. I have since procured one and am in search of one. They were black with a periodic table-type emblem on the front that read something like "Pb 12" and were made of neoprene I think. I can only find them for current model macs and would love to have one, but Google isn't having much luck finding this one.
Thanks guys/gals
