Molded in a light gray plastic, there is some flash on a few parts, but nothing major. The smaller parts are delicately molded and have good detail. Most of the ejector pin marks are located in areas that should be easy to take of. Decals look good, but more on that later. The cockpit glass has part of the fuselage molded with it so blending it in should not be too bad. A full set of clear parts is included so I suppose it might be possible to build a bomber version if you were up to it.
The instructions are very well done and include a parts list and a 3-view. The last page includes a color listing for Humbrol, Model Masters, Aeromaster, Tamiya, Gunze Sangyo and Revell. It gives you the number of the paint, but not the name. The assembly steps are well drawn and consist of 25 steps.

As for construction... There is not one part of this kit that didn't need cutting, trimming, grinding, bending, hammering or modifying in some way. Make sure you have plenty of sandpaper and filler, you're gonna need it!
The decals are also crap. They splintered as soon as they came off the backing. I coated the remaining decals with sealer and didn't have any more trouble.
