※ "304" is a symbol representing a type of stainless steel, and it has the same properties as surgical stainless steel. Color: Silver Size: Length: 50mm Wire diameter: 0.7mm Ball part: 2mm Quantity: 50 pieces (+ spares) Since the wire diameter is 0.7mm, it has stiffness and is firm. The ball part is a large 2mm, making it difficult to come out. [Note] We basically include 1-2 extra pieces for weighing purposes. There may also be some bent pieces. (If you are concerned about this during your crafting, please use nylon pliers to smooth them out.) Please be aware of this beforehand. As this is a foreign-made product, there may be some dirt, misalignment, minor defects, deformation, and size errors. Please consider this before purchasing (*μ_μ)♪
