Ruloid ruler pen without ink | eco-friendly gadgets

The Ruloid inkless ruler pen is an innovative and sustainable solution for everyday writing. Made of recycled aluminum, this pen uses advanced technology that eliminates the need for traditional ink: the metal alloy tip gently oxidizes the paper, producing a pencil-like mark that is completely erasable. The hexagonal barrel design integrates a handy ruler graduated in both centimeters (up to 11 cm) and inches (up to 4 inches), turning this writing instrument into a multifunctional accessory ideal for office, school or technical use. The capacitive eraser at the end also allows for use on touch screen devices, making the pen perfect for those who work alternating between paper and digital media. With compact dimensions of ø9×150 mm and a weight of only 17 grams, the Ruloid is convenient to carry with you at all times. Oxidation writing provides virtually unlimited durability, eliminating the need to replace refills and significantly reducing environmental impact compared to traditional pens. Thanks to its recycled aluminum surface, this product lends itself perfectly to personalization with a company logo, becoming a distinctive promotional gadget that communicates attention to innovation and sustainability. Ideal for corporate welcome kits, training events or as a quality corporate gift.
