4-piece "Classic" assortment of water-based acrylic paint markers, multimedia, glossy finish. The Skrib Acrylic Marker must be primed before use. Shake the marker vigorously to get the ball moving. Then, press the tip onto a sheet of paper several times to saturate it with paint. Re-prime each time it is necessary. The tip can be changed by twisting. The Skrib markers can be applied to most light cotton or synthetic fabrics. Once the applied product is dry, the color must be fixed by an adult after 10 to 30 minutes of drying time (depending on the thickness applied) at room temperature: either by ironing on the cotton setting (no steam) on the back of the fabric for 5 minutes or in a household oven for 5 minutes at 150 °C. The colors are machine washable at 40 °C without pre-washing and can be hand washed (except for metallic or pearlescent colors). Fabrics should be turned inside out to preserve the patterns during washing. The Skrib acrylic marker can be easily cleaned off the skin with water and soap before drying. For stains on fabrics, wash the surface immediately in hot soapy water. Repeat the process if necessary until the stain is completely gone. For more stubborn stains, the use of fabric stain removers based on bleach or active oxygen may be successful, as long as their use is compatible with the garment in question. It is recommended to use protective aprons when working with children. Keep away from wallpaper, painted walls, untreated wood, and other non-washable materials.
