Professional quality 36-color watercolor pencil set, in a tin case. - Brand: DERWENT - Model Name: INKTENSE - Number of Colors: 36 - Packaging: Tin case Thank you for viewing. This is a set of 36 Inktense pencils from Derwent, a professional art supplies brand originating in the UK. They can be used like regular pencils when dry, and when dissolved in water, they transform into transparent, vibrant ink-like colors. Once dry, the colors set and become waterproof, allowing for layering. Due to their fade-resistant properties, they can also be used on fabrics such as silk and cotton. The tin case has minor scratches from storage, but the pencils inside are almost unused. The new price is 9,350 yen (as of 2025.11.13) on Amazon. They are lighter than paints and easier to carry around for sketching, making them convenient for outings.
