Zero notes
It looks like the render, which almost never happens.

Better in person
The pigment is denser than any print I have bought. Zero regrets.

Packaged like a museum
Arrived in a rigid tube, ends taped, with a card inside. It felt like unwrapping something serious.

Gorgeous, slow to arrive
Worth the wait. The tone is richer than the screen suggests.
