I knew that these looked familiar to me.
I checked and found these---very close.
They may be Vacor that were marketed in the European market—I am still not sure----maybe Chinese.
Mojo will have the dibs on these for sure, drop him a line and I am sure that he will give you his best.

Mojo has posted a vriety of these in the past. I posted his latest link above.
Nice marbles!

Venwood, There are some nice marbles in that group.
The yellow and black one will spurn some interest on this board for sure. Does it have any Aventurine?--if it does---get us some more images.
Also the yellow and green Handmade---if there is any lutz--bring it on!
Marble--On!!
No, not damage, just an as-made machine made defect.
Not a Pontil, a cold roll, crease, fold, that did not roll into a smooth surface as the orb was made.
Marble--On!!
