I am trying to replace some glasses which I use. They are tourquoise-blue
and have a distinctly curved appearance and apparently were made by a
company called Valentino. Or the line was called Valentino? (They seem to
defy googling except that Neiman Marcus does show something by this
otherwise unknown manufacturer).

Does anyone know where I can find replacements or contact the company
please?

Not sure they are all that high quality or a collectable crafts item: The
colour seems to be a transfer.
