This premium, very smooth and well frosted, Atlantic Ocean tumbled roly pollies are in perfect condition. The green shades likely originate from 100-year-old bottle glass, likely Coca-Cola bottke remnants. They've been tumbling along Prince Edward Island shores for decades and hand beachcombed over many years.
The largest piece here measures right at one point three cm and the rest are smaller as photographed. US dime in photo for size reference.
Your pieces will arrive with a authenticity card describing the short story of sea glass and defining the ocean the pieces were found along.
