Howard Miller SuLiao-PDP-SandTimer 10 Minute Copper Sand Timer 5.1 Inch

Copper Sand Timer for Focused Intervals

This 10 minute hourglass measures 2.4 by 2.4 by 5.1 inches with a copper finish and black sand. It suits teachers, parents and office workers who want a visible, screen-free way to mark short work or play periods. The hand-blown borosilicate glass meets a ±10 % timing tolerance and thickened walls raise durability for daily handling.

Upgrade From Basic Plastic Timers

Replaces flimsy plastic hourglasses that crack easily or leak sand after a few drops. The jump is worth it when you need a timer that survives classroom passes, desk knocks and curious toddler hands without losing calibration. Glass thickness increased from 1.55 mm to 1.83 mm so the timer keeps its shape and accuracy longer.

Fits Any Flat Surface Without Power

Stands freely on desks, shelves or bedside tables and needs no batteries, cables or mounting hardware. The compact footprint leaves room for books, keyboards or décor while the sealed glass prevents sand spills. Not for buyers who need second-by-second precision, audible alarms or multiple interval settings in a single device.
