I've since seen this design on the web described as Holmegaard, but I personally don't think it is, unless someone knows differently. The white interior is quite thin unlike my other Holmegaard pieces, and the colour doesn't seem to match any Holmegaard glass that I can find during searches. Also, it isn't shown on the online Holmegaard museum or hardernet website. I'm still leaning towards Empoli, but just wondered what anyone else thought?
