Time is a fascinating concept that connects past, present and future and is far more than just numbers on a clock. ISSU ISSU understands time as something holistic and designs clocks that help children develop a fundamental understanding of it in a playful way while aligning with educational learning principles. Through consciously chosen colours representing the seasons, children learn to recognise changes throughout the year and develop a sense of time even before they can fully read a clock. At the same time, the clocks celebrate handwritten lettering, encouraging individuality and making a statement against complete digitalisation. Crafted from mouth-blown, sustainable glass, they combine lightness, durability and thoughtful design to create a timeless overall aesthetic.
