I love the size and dimensions of this mold 12x2.5x4. When I use a design such as a Taiwan Swirl, or a Chopstick Swirl and you cut the bar horizontally instead of vertically I can get three full 4" bars per row (3x4=12), whereas with my 10" mold I loose 2 inches (2x4=8). I love the quality of this mold and since it isn't wood I can wash it in the sink to remove any soap or color stains.
