Rulers tend to be one of the most straightforward tools in a pencil case—practical, reliable, and (let’s admit it) a little bit dull. But what if this everyday item could bring a burst of excitement to the classroom and spark some friendly competition? The Ninja Jumping Ruler changes the game, giving stationery collectors and snowboarding fans something new to rave about. This is no ordinary measuring stick. Drawing inspiration from the adrenaline-fueled world of snowboarding, the designer behind Monster Cliff’s core products has created a ruler that’s as much about play as it is about precision. The Ninja Ruler is engineered for bouts of “Ruler Battle,” a playful pastime where students show off their skills right at their desks, using their rulers for trick shots and daring jumps. Designer: Monster Cliff What truly sets the Ninja Ruler apart is its ability to leap and spin, just like a snowboard catching air. With a special groove and a rounded edge, users can flick the ruler with a pen to send it spinning, flipping, or even jumping across the desk. Its clever construction turns a humble tool into a miniature stunt board, perfect for anyone looking to add a splash of action to their stationery lineup. The mechanics are as simple as they are ingenious. There’s a slit or dent along the ruler where you can rest your pen. When you press and release, the ruler springs forward, sometimes spinning as it goes. By tweaking the angle or placement in the groove, you can experiment with different tricks, discovering new ways to make your Ninja Ruler fly and turn. A nod to snowboarding culture is evident in every design detail. The swooping curves and dynamic movement echo the feel of a snowboard carving down a slope. It’s a fun tribute from Monster Cliff, blending their board sports heritage with a classroom essential. The result is a ruler that isn’t just a tool, but a toy that encourages creativity, dexterity, and a touch of mischief. Of course, the Ninja Ruler is still perfectly functional for drawing straight lines or measuring homework. But its real charm shines when the bell rings and the unofficial “ruler battles” begin. School desks transform into mini arenas, with students eager to pull off the next big trick shot. For stationery collectors and snowboarding enthusiasts alike, this playful ruler proves that even the simplest objects can inspire big fun.
