Out of my collection:
divided core swirl marble
Size: 0.9 inches / 23mm
Condition: mint - original surface
made around 1900 in Thuringia, Germany
Registered and insured airmail postage from Switzerland is $17. Within Europe it is cheaper. Of course I will combine postage, I can send up to 15 regular marbles for the same postage.
If you have to pay right away I will refund the extra postage you get charged immediately.
Feel free to ask any questions :-)
