This Shinwa ruler is made of stainless steel and is 30cm in length. It's an ideal pocket rule and features a pickup rule design, meaning it has an upturned end for easy retrieval from flat surfaces. The precision ground and polished edge provides a smooth user experience. The markings are etched and black chrome plated, offering low-glare and corrosion-resistant properties, matching the rest of the rule's surface. Manufactured to Japanese Industrial Standard (JIS) B7516 grade 1, it ensures quality in material specification, heat treatment, and accuracy. The markings are in red for enhanced visibility.
