These are 20 cm long jumper wires terminated as male to female. Use these to jumper from any male or female header on any board. Multiple jumpers can be connected next to one another on a 2.54 mm header. Comes in one pack of 20 jumpers (colors shown). Each group of jumpers are connected to each other and can either be pulled apart in any quantity (from 1-20, of course) or kept whole based on you needs.
