Work
Great quality, many uses and works well with the gpio pins of any rpi. However, they do not fit into themselves, so the length you buy is the length you get, for better or worse.

The product you didn't know you needed in your drawer
These are the spare parts you don't know you need laying around lol. I cannot tell you how thankful I am that I've had these laying around being a PC builder.

the fit was a little tight. had to push really hard to get them on the pins. otherwise as described.

Male / female jumper wire set is handy, the color-coded makes it easier.
4 of these were used to connect a DS3231 RTC to GPIO expansion board connected to RPI 400B. I'll use these in future raspberry pi experiments. It's nice they are color coded to help you see what is connected to what. The wires are relatively thick (not flimsy) One of the connectors felt a little lose until I rotated it but now it works fine.
