The Low Temperature Sakura Solid Marker is a permanent solidified paint marker that is specially formulated for cold temperature environments, with a working temperature range down to -40°C. It marks on almost any surface- dry or wet, dusty, rusty or rough and can be used indoors and outdoors- even when raining or snowing. It is ideal for tough industrial marking on iron, steel, concrete, wood, rubber, paper, leather, glass, vinyl, and more! Paint goes on smooth right from the start- just uncap and start marking! The convenient twist-up mechanism advances the marker material easily. The 13mm wide tip can be trimmed with a blade to make finer marks. With paint in this solidified stick form, you can mark upside down, sideways, at any angle- with no dripping or mess, and no paint brush is needed. The quick-drying formula usually dries within 5-7 minutes and after drying, marks are permanent, water-proof, and fade-resistant. However, marks can still be removed from non-porous surfaces by using alcohol-based solvents.
