I prefer to not leave boards in places where stuff like pin headers can be
damaged. And really, pin headers are the least of your worries: they're easy to
replace and dirt cheap, unlike some of the more delicate and exotic components.

You can use what is colloquially known as a "DuPont connector", which is
designed to mate with pin headers. They're more typically used to run wires to
pin headers -- for example the front panel lights and buttons on a PC -- but
you can skip the wires when you only need a mechanical rather than electrical

A starter kit with the special crimp tool, header shells, and male and female
pins to fit in the shells costs around €30 from Amazon. Don't do what I did and
try and cut corners by just buying a cheap box of shells and pins and assuming
you can wing it with a regular crimp tool or pliers, because that just results
in a knackered connector and another Amazon order.

The kit will come with a variety of header shells and not just the 1x2 of
jumpers. Given that pin headers are quite gregarious, you'll find the larger
shells useful for capping and/or configuring multiple jumpers in parallel.
