Here you are offered a large filigree cartouche.    

This unusual item is NOT flat, but undulates around the edge.

It can be used as a pendant, a decoration on hats, bags or buckles. It could be used to decorate trinket or jewellery boxes too. I am sure you could have many ideas for this lovely item. 

This large cartouche measures 59mm x 43mm, at the widest points.
