Tinplate Paint Box for Solid Watercolour Pigments in Three Square Sizes

For artists seeking a dedicated and protective case for their solid watercolour paints, this tinplate paint box offers a practical storage solution. Its metal construction provides essential rigidity to safeguard delicate pigment pans during transportation between studio sessions or outdoor painting locations. The three-fold, square design efficiently organises colours within a compact form factor, making it a straightforward choice for painters who value orderly palettes. Supplied empty, it allows for complete customisation with your preferred brand and selection of watercolour pans, fitting seamlessly into a professional or hobbyist artist's toolkit.
Features and Construction

This product focuses on core functional elements: a protective metal build and a space-efficient folding design tailored for paint storage. The following details outline its material composition and the specific size options available to suit different quantities of pigments.
Material and Build
The box is fabricated from tinplate, which is steel sheet coated with a layer of tin. This material combination results in a sturdy and dimensionally stable case that resists bending or crushing under normal use, offering superior protection for its contents compared to softer cases. The manufacturing process noted is offset printing, which refers to a method for applying detailed graphics or text to the flat metal surface before it is formed into the final box shape. This allows for the application of colour charts, branding, or instructional labels directly onto the case exterior.
Size and Practical Fit
The paint box is offered in three distinct square size variants, each correlating to a different folding panel count. The smallest option measures 125 millimetres in length, 70 millimetres in width, and 23 millimetres in depth, described as a 12-folding box. The medium size is 220mm long, 70mm wide, and 23mm deep, designated as a 24-folding box. The largest option provides dimensions of 225mm in length, 110mm in width, and 28mm in depth, referred to as a 48-folding box. These precise measurements allow you to select a case that matches the number of pigment pans you intend to carry, ensuring an efficient fit without wasted space.
Uses and Placement

The primary function of this box is to house and organise solid watercolour paints, a need common across various artistic practices. Its design supports both organised studio work and mobile painting scenarios, providing a consistent home for your pigments.
Event or Professional Use
For plein air painters, workshop instructors, or artists attending live events, a reliable and robust paint case is essential. The tinplate construction protects valuable pigments from impacts in a bag or backpack, while the clearly defined compartments help quickly locate specific colours during time-sensitive work. The option for custom printing via offset means studios or brands can equip their artists with uniformly labelled kits, or individuals can add personal identification to their case.
Everyday Home Use
In a home studio, this box serves as a permanent, organised station for your watercolour palette. Keeping pans securely in place prevents them from shifting, mixing, or getting lost in drawers. The rigid lid can also function as a stable mixing surface or a clean cover to protect paints from dust when not in use. Choosing the size that fits your collection helps maintain a tidy and efficient workspace, reducing time spent searching for colours.
Benefits and Buying Value

The value of this paint box lies in its straightforward approach to solving a specific organisational need with durable materials and clear size options. It avoids unnecessary complexity in favour of practical utility.
Reuse and Low Maintenance
As a durable metal case, it is designed for long-term reuse. Unlike cardboard or flimsy plastic boxes, the tinplate body is not prone to wearing out or breaking from repeated opening and closing. Maintenance is minimal; keeping it clean simply involves wiping the smooth exterior with a cloth. Its empty state means it can be refilled endlessly with new or replacement pigment pans as your colours are used up or your collection evolves, offering lasting utility.
Why Choose This Product
Select this paint box if you require a no-fuss, protective case specifically sized for solid watercolour pans. Its key differentiators are the tangible choice between three precise square dimensions and the practical advantage of a rigid metal shell. It is a functional tool rather than a decorative item, making it a suitable choice for artists who prioritise organisation and paint safety. The availability of different sizes allows you to match the product capacity directly to your current and future collection needs.
