Easily mark the sides of your cake for perfect placement of accents, borders and more! Three marker pins snap into place along the edge of the vertical ruler with a stable base so you can mark the placement for decorations. Imagine being able to easily mark three parallel lines around your cake for evenly distributed side decorations. Or use it to divide your cake for evenly spaced garlands, drop strings, floral placement and much more. No matter why you need to mark the sides of your cake, this tool can help you get it done accurately and inconspicuously. So much easier than holding a ruler with one hand and trying to accurately mark with another. Hand wash.
