Product details:

Specifically designed to cut multiple layers, a rotary cutter with a 6 x 24 ruler attached makes measuring and making perfect cuts through fabric easier than ever. Great for beginners, the unique design of this tool makes perfect cuts through fabric a breeze. Since you're not managing two tools separately, you don't have to struggle with a misaligned ruler or worry about holding the rotary cutter straight. It includes a 45 mm spring-action rotary blade that makes clean cuts through multiple layers of fabric and an ergonomic blade carriage that makes cutting smooth and easy. The ruler features a bold 6 x 24 grid that is printed on both sides for right- or left-handed use, plus highlighted numbers for excellent visibility on light or dark fabric. The unique rail design prevents lint build up as you work, the no-touch magnetic blade change system makes blade change safe and easy while storing used blades, and a carrying handle offers easy, convenient transportation.
