The Drawing Gum Marker allows for easier use of the product and precise application with very fine lines. It needs to be prepared for first use. To do this, please: - Shake the marker vigorously with the cap closed until the internal ball is audible. - Then press the tip several times onto a sheet of paper to saturate it with color. It is advisable to regularly clean the marker tip after use by removing it from its holder and rinsing it under warm water. If any residue forms on the marker tip, excess material can be easily removed with your fingers. If necessary, a replacement marker tip is located directly in the cap. The marker should be stored horizontally and is durable for up to 12 months after first use at moderate room temperature (15 - 25 °C). Our marker is a true all-rounder. It independently replaces the Drawing Gum bottle, brush, and water container. This accessory is very practical due to its ease of use and only requires the selection of a suitable substrate for its application. It is a portable product that can be taken anywhere.
