Special blend of mediums to enhance transparency or aid in brushability and flow.
Brush Cleaner - Use this to keep your brushes in tip-top shape! Paint cleans with soap and water, but this mild cleaner will add extra protection to the bristles, keeping them looking good as new!
Duo Aqua Linseed Oil - This special blend of linseed oil should only be used with Holbein's Duo Aqua Oils. Do not use regular linseed oil with water-soluble colors. This medium will add gloss to the paint film.
