The manufacturing process led by Nousaku uses an ancient sand-casting technique, giving the pieces a unique rough surface texture and connecting them to historical traditions.

A defining characteristic of the S/N series is its use of blackened brass, achieved not through synthetic paint but rather a natural chemical reaction between rice bran and metal.
The name "S/N" is intentionally ambiguous, allowing for various interpretations such as 'serial number' or 'south north'.
Drawing inspiration from an Enzo Mari paperweight project, this intentional ambiguity reflects the designer's goal of "creating an object that does not emphasize its use in an inorganic form like an industrial part. Like using a found bolt as a paperweight."
As we celebrate ten years of the S/N series, we invite you to explore its thoughtful design and story with all of us here at Tortoise General Store.
