Recycled paint from stone sludge repurposes waste from the stone industry and can be mixed with natural pigments or granules for varied surface effects. The R2R Paint Tool Kit promotes this paint, designed for easy carrying, storage, use, and display. Eco-friendly principles guide the design, with the tool kit, measuring spoons, and powder bags made of paper. The outer box features a monochrome hot-stamped stone pattern, fully embodying environmental concepts and enhancing stone waste reuse.
