Poplar wood container with three compartments, respectively for the red powder, the water and the cotton lanyard. Tool used by sawyers and shipwrights to mark the cutting lines of planks. The lanyard, moistened and dyed with red powder, was put under tension along the line, then pinched so that it left a mark-imprint on the wood, therefore a colored line that acted as a guide.
