Antique Ivory Pyralin Dubarry Vanity Late 1800's

This Pyralin collection of vanity accessories dates back to the late 1800's. It is a nine piece vanity set with mirror, comb, finger nail buffer, finger nail file, finger nail cleaner, button hook, and three boxes One of the boxes has Ivorytone Pyralin Dubarry etched on the bottom. I tried to photograph the etching but they would not show up. This box is cracked at the hinge but opens and shuts with no problem. This box has a gold tone worn velvet lining. The box with the purple velvet inside lining has a hole in the back of the box as shown in the picture.

Additional information added after receiving question:

Four of the items have a stamp on them. The box with the purple velvet lining says Ivortus etched on the bottom and the box with the gold velvet lining says Ivroytone Pyralin Dubarry etech on the bottom. These boxes were originally owned by my 84 year old mother-in-law's mother and aunt. Unfortunately all now deceased and cannot ask them. Both the comb and the finger nail buffer have Ivory Pyralin etched on them. As for the other items I cannot find any marks on them but they are part of these sets
