Yes, I bought lots of this blaue abalone and for that pen I seem to remember it took 48" of the strip. I can't find it anymore except from the US, but the postage is far too much. I have some small bits of blaue abalone shell more than enough to make a really nice pen, but either my wife has thrown it out or it is hiding.
If I had spelled it right paua abalone I might have found it, here is some, that's where I bought mine.
