Using these jumper leads is easy. Just connect them to your mini breadboards for your projects. You can separate the leads from the strip as per your requirements to make mini ribbon cables. When handling, be gentle to avoid damaging the DuPont headers. Store them in a dry place to keep the cable's soft matte finish in good condition. Don't expose them to extreme temperatures as it may affect the quality of the stranded copper wire. With proper care, these leads will serve you well for a long time.
