I used this item once after purchasing it, but I'm selling it now as I won't be using it anymore. Features: Feature 1: You can create neat, parallel creases simply by aligning the guide with the edge of the cardboard and sliding it horizontally. Feature 2: With a rotating blade at the tip and a movable guide that follows the edge of the cardboard, you can easily adjust the blade to the desired height for cutting. Feature 3: You can easily create perforations within a range of approximately 25-270mm from the top of the cardboard. Size: Small, Color: White Usable Range: Approximately 25-180mm (from the top of the cardboard) Please refrain from purchasing if you are concerned about minor details. Thank you.
