Anyhow, these lenses aren't readily available because they lack popularity. I don't see these lenses often, if at all in shops. The general idea would be to pre-order these if you really wanted them, then wait a million years. I don't know if EOS still makes these..don't take my word for it.
However, I did come across a lens very similar but I couldn't find it. It went under a different name.."Vanny"? I don't know. It really doesn't matter, because I'm sure there are so many other 3 tone lenses that give off a similar effect as these. I'm sure you'll agree.
