Tomoe Soroban Book Stopper (4 colors: white, black, red, green) This is a clip-type book stopper that holds open pages. It prevents pages from falling over from one side to the other. I bought it but didn't use it, so I'm selling it. Normally, it costs 1,210 yen per piece online, plus about 700 yen for shipping. ■ Quantity: 2 ■ Size: W47 x D85 x H30mm ■ Material: Steel (resin coating) ■ Weight (per piece): 120 g
