A cast glass vase that is both compact and modular. Its triangular design allows it to be used as a standalone piece, or several units can be combined to form the desired composition. It can hold a single flower or a full bouquet. The corrugated surfaces of PRISM are designed to play with light and reflect its surroundings. The density of the glass changes due to the triangular shape and the hollow center, resulting in variations in the refraction of light and colour density.
