The set includes the parts to make five Panzer IV J Medium tanks. It comprises ten plastic part sprues, two Stowage sprues, two Tank Commander sprues, five sets of metal Schürzen, ten Rare-earth magnets & one Decal sheet. That's just about everything you could want in a box set, no word yet on the price so I'll be interested to see how it stacks up against the Plastic Soldier Company offerings.
Here's a couple of shots of the contents.
I like the idea of the one piece track sections and the detail looks fine, but I'll reserve judgement until I see the rest of the sprues. For me the key thing will be price. If I can buy a set like this for about £20 inc discount I can see me buying them, if they're £25 or more I think I'll stick with PSC as I'm not that bothered about the decals and magnets.
