This liner brush is designed for creating long, thick lines. It has bristles that are 15 mm long and 1 mm wide. Care: All our brushes have a protective wax coating. Therefore, before using it for the first time, clean the bristles with alcohol and a wipe to completely remove the wax. After each use, clean in the same way, with alcohol and a wipe. If using glitter, clean first with Base Coat and then with alcohol and a wipe. Do not use nail polish remover or acetone. Always reshape the bristles to their original form after cleaning to maintain their structure.
