This concept by 1/plinth studio is proof that industrial designers can find inspiration in the strangest of places — even in the very tools they use to make things. The design was dreamed up upon gazing at an abrasive disc that’s more commonly used for grinding or polishing surfaces. What the designers saw, however, was a set of 14 unusual coasters. Each disc in the stackable set has its own unique texture and color. Combined, they make for a unique conversation starter and add touch of industrial style (and ring protection!) to your tabletop. Designer: “The 14 coasters possess a different tactile sensation in order to engage the user and allow a different experience depending on the type of coaster and type of cup used,” 1/plinth studio told Yanko Design. These coasters have holes in the middle made up of a 4-inch diameter disk, similar to a doughnut, and can be stacked on top of one another on a rack. The rack comes in two size options. Its lid and bottom pad are made up of abrasives similar to the coasters which it holds.
