This is a 55mm CHONK SENIOR. 
This Exclusive Chonky has a liquid core eyeball that spins when rolled!

Like a shard carved from a frozen scrying pool, Watcher’s Glacier is a striking 55mm d20 in deep arctic blue, housing a sharp, eerie eyeball suspended in magical frost. With shimmering silver numbers and hypnotic clarity, this die is more artifact than tool, perfect for diviners, frost mages, or GMs running icy realms. It’s less about fair rolls and more about commanding presence at the table.

Each order is for only a single 55mm d20.
A  great addition for intermediate-level dice collectors!
