Files from this series are valued by modellers worldwide for their unique combination of durability, reusability, and ergonomic handling. This set includes ten modelling files (so-called sanding sticks) in five different grits; each grit has two files: 180, 240, 400, 800, 1200. Thanks to this, Ultimate Modelling Products UMP020 Thinny Sticks Multi Pack B is perfectly suited for a variety of tasks: from rapid surface sanding and material removal (grits 180 and 240), through smoothing and preparing surfaces for painting (400, 800), up to final polishing of details with the ultra-fine 1200 grit. A key feature of Thinny Sticks is their flexibility – this allows comfortable adaptation of the file to hard-to-reach places and crevices, where traditional tools may be insufficient. The files are made from durable high-grade foam-based material and a tough, delamination-resistant abrasive layer, which increases their lifespan. The product is washable, so it retains its abrasive properties much longer than classic paper files – simply rinse it under running water and let it dry.
