Professional Plastic Ring Mandrel Sizer for Accurate Jewelry Measuring Whether you're a professional jeweler, jewelry designer, repair technician, online jewelry seller, or DIY jewelry enthusiast, this plastic ring mandrel provides fast, reliable, and accurate ring size measurement every time. Designed using the standard US ring sizing system, the mandrel measures sizes 1 through 15, including half-size graduations, making it suitable for accurately checking ring sizes, resizing existing rings, and creating new jewelry pieces. Unlike standard smooth mandrels, this model features a grooved back side, allowing stone-set rings to sit properly during measurement. The groove helps protect raised gemstones while providing more accurate sizing for engagement rings, wedding bands, gemstone rings, promise rings, fashion rings, and custom jewelry. Constructed from durable lightweight plastic, the smooth professional finish allows rings to slide effortlessly across the surface without scratching. The clear white engraved markings are easy to read, helping improve measurement accuracy even during frequent daily use. At approximately 12.5 inches in length, the mandrel offers comfortable handling while remaining lightweight enough for portable use. An integrated hanging hook makes storage easy in workshops, jewelry studios, retail counters, or home craft rooms.
