Handcrafted Marble and Wood Perpetual Desk Calendar in Black 'Eternal Time'

"Sleek and endlessly reusable, this perpetual calendar transforms date-tracking into something almost cinematic. Mexico's Sierra Family carves each component from black-toned marble and hand-painted pinewood and cedarwood, assembling five blocks that rotate to display any month and date you need. The black and white aesthetic creates striking depth, making this holder-and-block system a bold statement piece that also keeps you organized."
