Bill said it all.

No, Bill forgot to mention the smell

.
Acrylic, if it has a smell, does so like glue -> glue-sniffer

. Celluloid has, IMO, a pleasant, old-fashioned, camphory smell.
Also, celluloid doesn't break very easily at all, it is very flexible, whereas acrylic materials aren't

Warm regards, Wim
