Boker imitation tortise shell?

I was looking at the Boker trapper lock with the imitation tortise shell, and I was wondering if the handle material is delrin or celuloid that bleeds out and self destructs after a time like the old celuloid?

In the Boker catalog, they call it celluloid. No mention of any reformulation.
I threw caution to the wind and bought one anyway. It sure does look nice.
I keep it in a well ventilated, cool, dark location when I'm not carrying it.
Time will tell.
