This is a 55mm CHONK Senior. 
 
Like an ancient gem plucked from the heart of a forest, Emerald Core is a stunning translucent green 55mm d20, with crisp white numbers and a bubble-filled core that adds a hint of wild unpredictability.
 
While functional, it’s a showstopper more than a precision tool, making it an ideal display piece for DMs who want to leave a lasting impression at the table. Perfect for moments where nature and magic intertwine, or when you simply want to dazzle.

Each order includes a single 55mm d20.
The smaller die shown is for comparison only and is not part of this listing.
