The Raw
Materials
Explained
Four natural rattan materials.
One signature craft.
Every basket begins with the right material. At Nithya Boutique, we work with four distinct rattan materials – each with its own origin, character, and purpose. Understanding what goes into a basket helps you choose the right one for your home, garden, or storage needs.
🌿 Koboo Natural
Kubu Natural · Kobo White
Koboo (also spelled Kubu, Kobo, or Kooboo) originates from Borneo, Kalimantan, Indonesia. Local names include sega, lunti, or runti depending on the region.
In its natural form, Koboo is white or yellowish – the unprocessed, raw skin of the rattan vine. It gives baskets a clean, light, organic look and is one of the most popular materials globally for storage baskets and home décor.
Why it's valued
- Lightweight yet strong
- Natural warm tone suits any interior style
- Holds shape well after weaving
- Takes colour dyes easily if coloured finishes are needed
🪨 Koboo Gray
Kubu Grey · Kobo Grey
This is the same Koboo rattan – but put through a special colour transformation process. The Koboo Gray process involves soaking rattan in water for fermentation for 2–4 weeks using natural plants.
Uniquely, this process only produces its distinctive grey in the Majalengka region of West Java – the local soil and water chemistry are irreplaceable. Koboo Grey requires almost no chemical processing, making it one of the most eco-friendly woven materials in the world.
Key characteristics
- Distinctive warm grey-brown tone
- 100% natural colouring – no synthetic dyes
- Each batch varies slightly; every basket is unique
- Requires expert control of fermentation for consistent colour
🪵 Rattan Core
Fitrit
Rattan core (also called Fitrit) is rattan that has already been peeled – it has no skin. Typically made from Kubu or Sega rattan, its exposed surface absorbs colour far more readily, meaning it can be dyed into any shade.
It is a semi-finished material produced by splitting raw rattan. The species most commonly used are Sega (Calamus caesius) and Lambang (Calamus ornatus).
Role in basket production
- Used as the structural frame or inner skeleton of a basket
- Also used as vertical weaving lines alongside skin materials
- More uniform and consistent in shape than whole rattan
- Easier to bend and shape into complex basket forms
⚙️ CL Rattan
Ce El · CEEL · SEEL
CL is a heavy-duty rattan material with substantial canes and remarkable sturdiness. The colour tends naturally towards reddish or brown tones due to the village production process, where diesel fuel is used in rattan cooking.
High-quality CL showcases rich red hues; lower grades lean towards darker brown. Weaving CL demands physically strong, experienced artisans – its weight and rigidity make it unsuitable for fine decorative work, but unbeatable for durability.
Best used for
- Heavy-duty outdoor or garden baskets
- Fireside log baskets
- Large storage baskets carrying significant weight
How They Work Together
Material at a Glance
In high-quality basket production, manufacturers often combine multiple rattan materials – and sometimes natural fibres like banana leaf, seagrass, and water hyacinth – to achieve both structural strength and aesthetic appeal.
| Material | Type | Role | Best For |

The Craft
The Skill Behind
Every Basket
The skill of a manufacturer lies in knowing which material combination to use for each basket type – balancing weight, durability, weave style, and visual finish. Every basket we carry at Nithya Boutique reflects that expertise.
