Freehand? Creative Techniques? No Problem with Elumen thickener.
Shake well before use. Add drop by drop (max. 10% with recommended amount for freehand at 5%). Mix until desired consistency is achieved.
*Notice! Avoid using more than 10% as it may lead to color shift and low performance of the color. DO NOT mix with Elumen Play as it could lead to unpredictable color results *
