Nine colored circles arranged in a grid pattern represent the Tokyo Metro lines, each labeled with a single letter (G, M, Mb, H, T, O, Y, Z, N, F) in clean, modern typography against a soft peachy-beige background. The composition is orderly and graphically striking, presenting the transit system as an accessible visual reference with its Japanese title "東京メトロ" and English subtitle at the top. Crafted from dishwasher-safe stainless steel and made to order, sized to fit a standard bottle and keep it cool for hours, with the artwork wrapped around the outside. It holds the centerpiece of the table and doubles as an independent artist's work.
