Magnetic Tumbling Pins - 0.3mm X 5mm

With a thinner 0.3 mm diameter, these specialized magnetic pins are designed for the most intricate and delicate jewelry designs. They are able to penetrate into micro-settings, tiny filigree gaps, and the internal galleries of rings where standard 0.5 mm pins might get stuck. Despite their smaller size, they are incredibly effective at burnishing the metal and removing the dullness from cast surfaces. These pins are a must-have for jewelers working with high-detail 3D printed or hand-carved castings that require a thorough internal and external finish without any damage to the design.
