5 Cricut pens with a fine 0.8 mm tip for your customization projects. These pens produce vivid, quality color transfers that last over time. 5 colors: red, green, blue, brown, black. Requires a customizable substrate compatible with Infusible Ink and a Cricut EasyPress 2 or a heat press that reaches 205°C (400°F). Unlike vinyl or iron-on flex where the design is attached with an adhesive, Infusible Ink fully fuses with the material and allows the ink to remain in the fiber. With Infusibke Ink, you will have brilliant, perfectly smooth transfer results that do not come off, do not fade and are wash-resistant. Please note that the Infusible Ink technique does not work on cotton, make sure you use polyester. Cricut reference : 2006257.
