I used these, which are apparently 3D printer nozzle cleaners (🤷🏻♂️) but work perfectly once you cut the end off.
KeeYees 3D Printer Nozzle Cleaning Kit, 10pcs 0.4mm Needles with Tweezers, Stainless Steel Extruder Nozzle Cleaner, Alternative of Drill Bits for 3D Printer
I did spend about 10mins debating with myself over the merits of using 5 needles v 8 or all 10 but then gave myself a mental slap and got on with my life (while using 5 needles!)
