I've just ordered an Aurora Optima Nero Perla (cracked ice) color fountain pen.  What I want to know is "Auroloide" plastic resin or celluoid?  Thanks.

The nibs .com website (http://www.nibs.com/...-nero-perla.htm) calls it " pearlescent celluloid", hence the confusion.  

Thanks.

I've got an early (plain 14k nib) made with what they call Auroloid, and it has shrunk a little just like some of the old celluloid.

I understand the recipe was altered years ago to prevent this.  So maybe it used to be true celluloid but no longer?

I'm not criticizing the material.  I like the character.

Is celluloid a plastic resin?

Auroloide is a type of cellulose acetate. Celluloid is cellulose nitrate and is more unstable.

The earlier AURORA Optima shrinks because the dye they use has some problems.
