Callus

Callus is an unknown business that appears in GTA 6.

It seems to have a physical store inside the Evergreen Shopping Center in Waning Sands, as evidenced by a sign outside the mall shown in Trailer 1.

Currently, it is unknown what type of store Callus is, though it appears in a mall alongside other fashion-based retailers.

The word Callus tends to refer to an area of skin that has become hardened over time, due to friction.
