Fantasy Skeletons, they look pretty cool and were easier to put together than you'd expect looking at them
One sprue of 12 contains 12 slightly different designs, all in the vein of "small rocks and gravel". They're also a good height and seem compatible with standard beveled GW 25mm rounds, and suitable for 2mm magnets.
One will need bases for the sprues one purchases. The sprues are a great value so what's an additional buck or two. One requires these bases for any Calvary units.
These are pretty good! Not a ton of fine detail or weapon choice, and many of the weapons are a bit too small and broke in transit, but the scale works OK for regular 28mm human arms to be swapped on and give you a bit of variety.
One tip: Frostgrave scales are all over the place but their Cultists 3 sprue has compatible (i.e. small, thin) arms. Combining the two sprues gives you a lot of options for a halfling skirmish warband or adventuring party with crossbows, axes, interesting swords, flaming torches, ropes and so on. The cheap Dark Age Irish warriors set also has some compatible shields and heads (plus bonus dogs!).
Overall a nice base for kitbashing a little halfling warband for very cheap.
