Topic: ID help needed - four czech tumbler

[lowersaxony]

ID help please ... 

Iam looking for the maker of this tumblers: moulded purple glass, the silver foil label reads "Leadcrystal Handcut".
Height 9cm and Ø 10cm. I can't find informations in my books or in the www.

Thank you!
Kevin

Interesting label - especially as the glass is not cut.

Are they neodymium glass Kevin? (Do they change colour under different lights: e.g. low energy bulbs, fluorescents, etc?)

indeed ivo... there is not a single cut 

yes anne, they do change the color, it seems to be alexandrite glass.

thank you!
