As I showed in this post, the packaging is a robust plastic case - a video cassette case in fact, if you are old enough to remember these things. Inside the case are a number of sealed bags containing the components, no sprues are involved. The components were obviously attached to some kind of frame/sprue as there are little remnants of these on most parts, some larger than others. Click on the photo for a closer look, I have kept the photos large so you can get a good close look at the bits.
The photo shows the contents of one bag - enough bits to make eight figures, including a command group. There are two each of four designs of legs and torso, plus a spare torso for a command figure. There are eight pairs of arms, which seem practically identical to me. There are also eight weapons being held by two hands, plus a couple of weapons held by one hand, a banner and a pointing hand, and a few other command bits. Finally, there are ten heads. Oh and there are square plastic bases included.
The plastic is not the same as GW plastic. It's a fair bit harder, so it's more difficult to clean away mould lines and any extra bits. You will need clippers to remove the extra little tags, a knife will prove hard work. Some of the weapons are a little bent, but it's easy to straighten them out with a little gentle bending of the handle. I would say that the level of detail held in the plastic is good, maybe marginally less crisp than GW can achieve, so less sharp edges than you might be used to.
That's all I can say at the moment, it will be a while before I get round to assembling any more figures and painting them. Hopefully the large pictures and my initial observations will prove useful if you are thinking about adding these to your collection.
