This drawstring bag is just the right size for a 30cm ruler. It's made of light blue fabric with a star pattern. A tape is sewn on for writing a name. Made with quilted fabric, so the corners of the ruler won't get rounded off even if bumped, and it should last a long time. The pattern may appear differently from the photos depending on how the fabric is cut. It will be folded for shipping. Please shape it before use. #ruler case #ruler holder #30cm ruler #drawstring bag - Design: Light blue star pattern - Material: Quilted fabric - Purpose: Ruler holder - Accessories: With string Thank you for looking.
