The most prominent feature of this design is the lid, shaped like a pebble. A small modification, yet enough to create ripples in the user's heart, evoking memories of joyful rural childhood. In those early years, riverbank pebbles were treasures waiting to be discovered whenever sunlight spilled onto the river's edge. Smooth stones, like gifts from nature, held the essence of countless stories. They were witnesses to the river's flow, carrying tales untold.

These stones bore the marks of time, polished by the years into roundness and enhanced beauty. Each one was unique, much like the distinct radiance of every moment in life. Perhaps, deep within each person's soul, there exists a riverbank, a collection of personal pebbles, leaving behind warm memories and traces of happiness.
