Hot Wheels x Daniel Arsham Eroded Twin Mill
HPJ32 turns Hot Wheels’ original twin-engine fantasy car into a sculptural art release. Arsham Pink color and molded crystallized erosion set it apart from standard Twin Mill paint variations.
What Is the Eroded Twin Mill?
The Twin Mill is a Hot Wheels original design, first released in 1969 and not based on a production car. HPJ32 is a later, separate art collaboration. Its defining feature is the sculpted crystallized erosion across the body, a molded surface treatment rather than printed decoration.
Mattel specifies a Silkstone body, ZAMAC chassis, Arsham Pink body color, and matching pink Real Riders five-spoke classic wheels. Those construction details, together with the HPJ32 code, identify this release.
How to Identify HPJ32
- Match the HPJ32 number on the package or product record.
- Look for raised and recessed crystallized erosion details across the pink body.
- Check the matching pink Real Riders wheels and ZAMAC chassis.
- Do not identify it by pink color alone; the sculpted surface treatment distinguishes it from ordinary Twin Mill color releases.
Collector check: The erosion is part of the body’s sculpted treatment. Look at the engine area, hood, and side panels from more than one angle to distinguish the relief from paint wear or surface damage.

Packaging and Condition
For a loose car, inspect the sculpted edges, exposed engine details, wheel finish, and chassis for chips, rubs, or residue. Close angled photographs show the surface relief more clearly than a single side view.
For a packaged example, check the package for cracks, bends, or seal damage and confirm the HPJ32 marking matches the car. Compare any included display pieces or paperwork with the seller’s photographs before treating the set as complete.
Variation Summary
The 2024 Mattel Creations Eroded Twin Mill is the documented HPJ32 issue. Its pink color, Silkstone body, ZAMAC chassis, and sculpted erosion form a distinct release identity within the broader Twin Mill family.
See the Eroded Twin Mill casting guide for its release record and the complete Twin Mill guide for the wider variation web.
