These earrings represent the "
Exploding Dots" developed by
James Tanton as part of the
Global Math Project, and are the perfect accessory for Global Math Week!
These are about 16 mm in diameter (total size is ~18mm), and should be robust enough for daily wear. If you are interested in larger ones, please let us know!
Note that these earrings do not include earring backs, but the posts are the standard size (.85mm diameter).
