The marker has a resistant 2-3 mm thick round nib and is available in many amazing colours and neon tones. For limited use only on polyester, as it can often cause the ink to run. For writing on polyester (e.g. sports strips) we recommend the edding 8040 laundry marker. Edding Textile Markers is ideal for creating colourful designs on most untreated soft textiles like cotton, silk, and linen. It makes textile designs easy. The round bullet nib has a stroke width of 2 - 3 mm. The ink is water-based pigment ink is odourless, does not run during the application, dries fast and extremely lightfast. After fixing the colours, ironing the fabric (without steam), the textile design can be washed at up to 60°C. Perfect for personalizing shoes, hats, backpacks, T-shirts, cushions, placemats etc. Available in 20 brilliant colours. Made in Germany. How to Use - Before drawing, place a piece of cardboard under the fabric to ensure that the ink will not bleed through the material. Once completed with the design, the applied ink can be made permanent by ironing once (without steam), and wash-resistant up to 60 °C. Note - Secure the fabric with double-sided adhesive tape to paint on a non-slipping and fixed surface. Use with caution on polyester as the ink can spread. It's recommended to use Edding 8040 Laundry Marker instead, which is available in black or red. Store textile marker horizontally.
