Unapologetic, rugged, and heavy. Our 28-gram Cast Iron die celebrates pure industrial metallurgy. Unlike stainless steel, raw cast iron darkens and matures over time, developing a deep, gunmetal-grey patina with a distinct, tactile grain texture that feels like a vintage heirloom in your palm.
Machined from dense, solid iron billets, we carefully preserve the natural grain structure of the metal to give each die a subtle, authentic industrial texture.
Keep dry: Just like a favorite cast-iron skillet, raw iron can rust if left wet. Wipe clean after use and let your skin oils naturally seal and darken the metal over time.
It has a raw, steampunk aesthetic that no polished steel can match—growing darker, richer, and more rugged with every game you play.
If you are in-between those sizes,
we recommend ordering the upper limit.
