Sakura Solid Marker Slim, initially designed for industrial use, has quickly gained popularity among writers due to its ability to mark on virtually any surface. This solidified paint stick works on oily, greasy, muddy, snowy, rough, and smooth surfaces, making it ideal for both indoor and outdoor use. It even marks and dries underwater. Thanks to its fast drying time, it becomes permanent in just a few minutes and is virtually odorless. The 'Stay Fresh' twist mechanism keeps the paint ready for action, allowing it to mark on materials like wood, fabric, plastic, steel, and concrete. Like other markers in the Solid Markers range, Sakura Solid Marker Slim produces a 9 mm mark and can be easily restored by trimming the dried tip if necessary.
