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 eco-friendly bamboo with a glossy printed surface and made to order, hand wash only. A coffee table platter, entryway catchall, or breakfast-in-bed carrier that carries an independent artist's work, not a store-shelf print.
