A pair of Shur Grip Z cables in size SZ329. You can look up the sizing chart online to see if they'll fit your tire size. They've been used once. They're in perfect condition, are quick and easy to install, come with the bungees to keep them tight, and are low profile so they won't hit things on the inside of the wheel or fender. Very smooth to drive on, and provide excellent traction. The last photo is what Z cables look like installed. The diagonal pattern of the cables is what makes them drive smooth, and have so much grip.
