Walnut Folio Watercolor Kit — a leather-bound watercolor studio that opens like a vintage book and tucks into any jacket pocket. The folio (95 × 75 × 35 mm closed) is built from solid black walnut wrapped in full-grain leather, with a brass snap closure and a 4-panel layout that includes a built-in paper holder, 12-grid paint wells, a mixing tile, and a sponge well. It comes with a brass travel brush, 20 pcs of 100% cotton watercolor paper (300 gsm cold-press, 80 × 54 mm, refillable), a mini water vial, and a mini spray mister. Available with or without Schmincke Akademie® paints. Perfect for plein air painting, travel sketching, café sessions, and lap-painting — no flat surface required. Beautifully presented in a gift box, making it an heirloom-quality gift for artists who value portability and craftsmanship.
