The erasable Frixion Colors are felt tip markers that contain thermo sensitive gel ink. The heat generated by friction when rubbing the paper with the special tip turns the ink invisible. With no damage to the paper, you can erase and instantly re-colour over your mistakes.
Great for planning or using in your bullet journal you can even create interesting effects by rubbing out sections of block colour. The markers are also great for sewing as you can draw on fabric and then erase the ink by ironing over it. Frixion Colors are available in a wide range of colours. Note: Do not use Frixion Colors when signing legal documents, cheques, or when writing exams.
