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. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
