Vacor has many types of marbles that they may refer to as “frosted”. This one is a “Caterpillar”, a frosted version of a “Bumblebee”.
Beware however because there are a few folks selling marbles that have been tumbled in a rock tumbler that are being sold as “beach glass marbles”.
Beach glass marbles in their own right are a collectable marble—if you are into to these make sure that you are buying from a respected and well known beach glass collector.
Marble—On!!
