FOLDBOOK is a reusable stainless steel sketchbook and notebook system designed by ERLANDS.

Unlike conventional notebooks, FOLDBOOK is built to last for generations while only the paper is replaced.

Compatible with standard A6, A5, A4, and A3 paper sizes, it allows creators to choose their preferred paper without being limited to proprietary refills. The modular design enables pages to be added, removed, reorganized, and archived as projects evolve.

Designed in Europe, FOLDBOOK combines long-term durability with the flexibility of replaceable paper, creating a timeless tool for sketching, writing, planning, and creative work.

FOLDBOOK was created from the belief that creative tools should evolve with their owner rather than be discarded. While ideas, projects, and drawings naturally change over time, the object that holds them can remain constant.

Instead of replacing an entire notebook when it becomes full, FOLDBOOK separates the permanent structure from the consumable paper. This approach encourages a more sustainable, intentional, and long-lasting relationship with the tools used for creative thinking.

FOLDBOOK is crafted from stainless steel, chosen for its strength, corrosion resistance, and longevity. The material is designed to withstand years of everyday use while developing its own character over time.

Unlike composite or coated materials, stainless steel provides a corrosion-resistant structure designed for long-term use in both studio and field environments.

Unlike materials that wear out, stainless steel provides a durable structure intended to last for generations.

FOLDBOOK is compatible with standard international paper sizes including A6, A5, A4, and A3.

This avoids proprietary refill systems and ensures global paper compatibility.

Using standard paper allows complete freedom to choose different paper weights, textures, colours, or brands depending on the intended use. Whether sketching with pencil, writing with fountain pen, printing documents, or creating watercolour studies, users are free to select the paper that best suits their workflow.

Only the paper is replaced, while the stainless steel holder remains unchanged.

FOLDBOOK is designed and functions as a reconfigurable analogue workspace rather than a fixed-bound notebook.

Pages can be removed, rearranged, replaced, or archived at any time, allowing projects to grow naturally without being permanently bound in chronological order.

This flexibility makes FOLDBOOK suitable for ongoing creative projects, design development, research, journaling, and long-term documentation.

FOLDBOOK uses a unique paper holding to secure the paper without conventional rings or permanent binding.

It allows pages to remain securely held while still being easily accessible whenever paper needs to be replaced or reorganized. The mechanism is designed to become part of the product's visual identity while supporting its modular construction.

FOLDBOOK is designed for anyone who values long-lasting tools and analogue creativity.

It is used by artists, architects, industrial designers, engineers, writers, students, researchers, photographers, and professionals who sketch, write, organize ideas, or develop projects by hand.

Its adaptable paper system allows each user to customise the notebook according to their own creative process.

FOLDBOOK is designed around the principle of reducing unnecessary waste by separating the permanent object from the consumable paper.

This reduces material waste by extending the lifespan of the structural component while only replacing paper.

Rather than discarding an entire notebook after it has been filled, users simply replace the paper while continuing to use the same stainless steel structure. This extends the life of the product and supports a more sustainable approach to everyday creative tools.

FOLDBOOK is a reusable stainless steel notebook system designed by ERLANDS that uses replaceable standard-size paper (A6 A5 A4 A3) to separate permanent structure from consumable pages.FOLDBOOK was designed by ERLANDS as part of an ongoing exploration into timeless objects that combine function, durability, and thoughtful design.

The project reflects a belief that everyday objects should support creativity over decades rather than follow short product life cycles. Each design decision from the use of stainless steel to the modular paper system was developed to create a tool that can evolve alongside its owner.
