MIG Productions is respected around the world for their superlative military modeling supplies and accessories. In addition to their huge selection of pigments and finishing products, they also offer very fine resin accessories and photo-etched metal parts.

This is a set of photo-etched metal hexagonal bolts, as illustrated below. A million and one uses! The especially cool thing about this PE set is that the parts are not connected to the fret at all, so there's no clean-up needed--just peel the parts from the adhesive backing, and you're ready to go!
