This 22 AWG stranded hook-up wire bundle with dispenser box contains six 25ft. spools of red, black, white, yellow, green, and blue wire wrapped around reusable plastic spools.
Stranded-core wire is best used for wiring where there is bending or movement expected. It also works well with terminal blocks. It's not great for use with breadboards (without tinning). The wire is easy to solder to, and when bent it keeps its shape pretty well.
The box has a wooden dowel rod to hold the spools in place and let them spin, and there are little punch-outs you can pass the wire through.
