Vase-21 is a vase designed to hold exactly 21 flowers — no more, no less. Made of stainless steel, it features six circular openings: one for a single stem, one for two, then three, four, five, and six — each growing proportionally in size, echoing the quiet rhythm of accumulation. 1+2+3+4+5+6=21. Together, they form a composition that invites to arrange, rearrange, and observe the balance between structure and spontaneity. Designed in 2025 by Non-Objective↗ and released by Apropos Editions↗, this is the first object in a series exploring the poetics of numbers. Produced in two sizes, Vase-21 marks the beginning of an ongoing study into how numbers shape rituals, gestures, and space.
