Lots of dupont wires.
So many color, pin combinations.
Where is the one you need ?

@vroemm, I don't mean to disrespect you, only to disagree with you. This is what I would recommend for holding Dupont cables:

They are one of the top reasons for circuits not working, both here on the forum, and with my friends at local groups. They fail so frequently, especially where the cable joins the plug. So many hours are wasted only to discover that a faulty dupont wire was the cause. I recommend avoiding them in favour of solid wire, laid flat onto the breadboard. You can easily tell when a solid wire has failed. It goes floppy! Where a component cannot be directly connected to a breadboard, usually a breadboard-compatible version of the component could have been purchased instead, if the shopper had thought for a little longer about how they would construct the prototype circuit and the final build.

@PaulRB I agree for a large part with you.

But the dupont wires have their useful moments.

And their place in a hobby room.

I will not throw them away.

Btw, breadboards are, for some cases, not exactly a perfect testing tool either.

If you throw away the dupont wires,  are you then not very far away from throwing away the breadboards also ?

The wires with the square crimp housings are usually not bad. Especially if one uses terminated wires from Pololu.com and they are used in crimp housing to bundle them together to plug in to female headers or to plug on to male pins.
For example, using a 1x6 housing

to hold wires for Gnd, blank, D13, D12, D11, D10 for an SPI interface, and a 2 pin housing for 5V and Gnd.

I buy 50 packs of female-female, female-male, and male-male wires in different lengths to connect things up

The wires with the round encapsulated ends can be more troublesome.

I love breadboards. I avoid using dupont wires whenever I can. As I said before, I use solid wire and try always to buy components that can be connected directly with breadboards. Like these, for example:

Using the short solid wires sure does help prevent things from getting lost in the jungle. Connections are easier to verify as well.

Actually when I make wire antennas I used to push the insulator back while making the cut, so it's insulated and also will cause less injury if it pokes someone in the eye. I now also make a small loop at the end.

Once had a little wire bending jig for making breadboard jumpers of custom lengths, but it disappeared and I've not been able to find a replacement. Anyone know where I could get one? (if they still make them).

Most of the problems I've had with the Dupont connectors are with the pin type. The female type fit snugly on pin header strips very reliably, I use them for almost everything... for proto boards I cut and strip my own solid conductor wires. It's better because you can control the length.

No technical PMs.
The last thing you did is where you should start looking.
