The overall detail is good, however there is some flash on the truss sections. A bit of trimming and filing easily removed the flash. The styrene parts easy to cut with a hobby knife or razor saw and can be painted with enamel or acrylic paints. I have had excellent results using Testors plastic model cement to bond styrene.

They are perfect on the bridge I'm building for my N scale model railroad! Have half the bridge done with these things and it's made life easier.
