Topic: (4) Four little colored Ashtrays -- Czech or not?

[antiquerose123]

 :hi: there.  Sorry have not been a round for quite a few days here -- been sick here.

Bought these colored little ashtrays (or maybe pin trays).  No box, but I recall many different types of these around from Diamond shape, clover shape...to many shapes.  All smaller, and colorful.

Are these Czech? And what date may they be from?

Thanks as always  :ghug:

*** IF you have some from this same type of Series (but different shape)
Please feel free to add an photo of what the *shape* is of yours. 
Nice to make a reference to their shapes here ***
