High-quality rosin core welding wire is easy to solder and has a smooth flow, fast soldering speed, and strong soldering point. It has great soldering ability and is especially suitable for circuit board maintenance, DIY, home improvement, cable/TV/radio/stereo/toys, and other electronic device maintenance.

If you want to make a kit, you'll need some solder. This 0.1 lb (about 50 grams) spool is a good amount, not too much (like 1 lb spools) and not too little (like those little 'pocket clip' vials).

This is "60/40" leaded solder with 40% Pb (Lead), 60% Sn (Tin), and trace Ag (Silver) and Cu (Copper). The spool of solder contains approximately 0.3mm diameter of lead-tin formulation. It is not lead-free solder, so it is not for lead-free/RoHS shops. However, it's a joy for kit builders, much easier than lead-free, and great for beginners. For flux, it contains a 'no clean' rosin core.

This diameter solder is best for finer-pitch SMT work, given its a skinny 0.3mm. You could use it for through-hole but you'll probably find it a bit tedious as you'll need to feed a lot of solder to fill in large pads.
