Sleek, simple and effective. Ideal for designing and learning about GPIO pins. The package comes with two in a zippered bag as shown. They look a bit fragile, so don't try to bend them (unless you want to break them in two!). They also protrude a few inches past the edge of the board, so obviously you can't encase them or use them in the final project. On the other hand, I think they could use a few more markers. to indicate orientation (e.g. which side should be next to the USB ports) and some color to indicate the power and ground pins.
