Premium 1-Piece Black Walnut Folding Watercolour Sketch Box 23x18x3.4cm

Create, organise and paint wherever inspiration strikes with this premium black walnut folding watercolour sketch box. Designed in a refined notebook-style format, it combines a compact paint palette, mixing surfaces and practical artist accessories inside an elegant natural-wood case.

When closed, the box measures approximately 23 × 18 × 3.4cm, making it compact enough for an art bag, backpack or studio shelf. When fully opened, it measures approximately 23 × 36cm and provides a spacious, organised working area for watercolour, gouache, sketching and outdoor painting.

The interior includes 27 small paint-pan positions, smooth mixing areas, four brush-holder holes, an independent pen slot and a removable metal wash cup. This thoughtful layout keeps frequently used tools visible and within easy reach while painting.

A magnetic closure helps keep the case securely folded during storage and transport. The wrist strap provides added carrying security, while the standard 1/4-inch threaded connection underneath allows the box to be mounted on a compatible photographic tripod for outdoor work.

The included phone holder can support a smartphone for reference images, tutorials or recording the painting process. A large clip can secure suitable paper to the upper working panel, creating a compact mobile painting station for parks, gardens, travel and plein-air sketching.
