For perfectly brewed tea or perfectly cooked eggs, rely on this classic set of Three Sand Timers from Kuchenprofi. Color-coding tells the exact time: Green for 3-minute, Black for 5-minute and Red for 7-minute. Each works like a mini-hour glass - turn upside down and when the sand drains to the bottom, time's up. Wipe clean. Each, 3" Height x .75" Diameter. Dimensions: .75" x 3" x .75"
