Material and construction Good material: tinning copper with an insulated skin for safety and durability. The breadboard wires are slightly soft, making it convenient to bend them for test connections. The wire set is designed for easy handling and repeated use in prototyping and testing. Variety of sizes and colors Colors included: red, yellow, white, black, orange, green, grey, and blue. The set provides doubleend wires with a Ushaped design and 24 AWG, maletomale. Lengths available: 2 mm, 5 mm, 7 mm, 10 mm, 12 mm, 15 mm, 17 mm, 20 mm, 22 mm, 25 mm, 50 mm, 75 mm, 100 mm, 125 mm. Quantities: 14 lengths, 40 pieces for each size, all supplied with a tweezer for ease of use. Easy to operate Includes 560 pieces of doubleend tinning wire. Solid wire supports quick jumper connections on a breadboard. The included tweezer helps insert or remove wires from breadboards without deforming the soft wire. Key advantages Lightweight, thin, and compact with a wide variety of specifications and colors. Insulated, with uniform insulation thickness that is easy to cut and peel. Tinning on both sides provides antioxidation and easy connections. Soft insulation offers good handling while providing resistance to pressure and temperature. Use scenarios Prototyping and testing: quickly assemble and reconfigure circuits on a breadboard during development or debugging. Education and labs: colorcoded wiring to teach circuit layouts and demonstrate different connections. DIY electronics projects: flexible lengths and colors streamline wiring for experiments, demonstrations, and small prototypes.
