This is a fully marked GNC Italian Porcelain bowl with lid. I imagine this is for decorative purposes as well as functional for jewellery or keep sakes.
This is old but unfortunately I cannot pin a date down through research. If anyone does know please do message me. I'd love to know more. CapodiMonte is as far as I have got. Italian makers marks are not so easy to find.
This item has been kept very well. No damage at all minimal signs of use.
Dimensions are 6inch round by 3 inches high.
