The design approach for the perfume bottle cap was inspired by the brand's core concept of layering. Eco-resin was chosen for its sustainable properties and ability to be layered with different colors. By selecting and combining colors, the cap was designed to visually represent the idea of layering. The process involved mixing various colors of eco-resin to create blocks with natural industrial imperfections, resulting in unique pieces that reflect the individuality of each scent.

The layering of eco-resin mirrors the layering of fragrances, creating a cohesive narrative from the bottle design to the scent experience. This innovative use of materials and design techniques ensures that each bottle of Synapse perfume is a unique and tangible representation of the brand's identity.
