How it works:
The ruler is extremely easy to use. Simply attach it to the center point of your canvas or board using a pin (included in the set). Then start drawing the radial lines in the order and spacing that suits your design.
• You can create a dense, detailed grid or leave more space for larger patterns.
• The triangle notches around the circular base act like a protractor, helping you mark equal spacing.
• Use the long straight guide lines to draw from the center outward — your lines will be perfectly straight every time.

Material, Quality & Usage Guidelines:
The WOW-Ruler is made of flexible plastic with a thickness of 1 mm. This material is thin yet strong enough for careful creative work. The plastic is clear and colorless, allowing you to easily see the surface beneath the ruler and precisely build your layout.
The ruler bends without breaking during normal use, but like any tool, it requires gentle handling:
• Avoid dropping the ruler, especially from height — this can damage the edges or cause cracks.
• Do not overbend or test its strength intentionally — any object can break under excessive pressure.
Care & Maintenance
• After use, gently clean the ruler if it has been stained with paint, markers, pencil, or pigment-based materials like cream-brush.
• Use warm water with a mild soap solution or gentle dishwashing liquid that is safe for both your hands and the tool.
• Do not use alcohol, acetone, solvents, or any aggressive cleaning products — they will cause the plastic to become cloudy and lose its transparency, which affects the visibility and comfort of use.
With proper care, your WOW-Ruler will stay clean, crystal-clear, and accurate for many years of joyful creativity.
