Oscilloglass is a unique mechanical hourglass that activates upon flipping, with components descending slowly due to gravity, mimicking a clock's mechanism. It measures time and provides a tactile experience of its flow through movement, sound, and vibrations. Its minimalist design allows appreciation of its intricate construction from all angles. Available in 5-minute and 3-minute versions, it adapts to different time needs. The 'Yoi' 3-minute version embodies a serene atmosphere with its color and materials, resembling the calm beginning of the night.
