The Jumbo Grip pencil for paper and panels is especially good for writing on plastic or slate panels or, alternatively, on CHALKBOARD FILM while at the same time also useful for writing and drawing on dark paper like, for example, inscriptions on photo albums. The high quality pigmentation of the lead means that the colour adheres to paper without the need of a fixing agent but it is still able to be washed from a panel with water just like a normal chalk. For best results in applying colours, the substrate should always be somewhat rough. Because of its thick, triangular barrel and soft grip zone, the pencil is especially good for use by children. The Jumbo Grip for panels and paper can be sharpened to a point with any pencil sharpener designed for thick pencils.
