Those of us that build scale model aircraft often find ourselves having to re-scribe lines of rivets. Quite often, to add detail and realism in other models like tanks, industrial machinery or gunplas too.
We may need them because the kit didn't have a good level of detail, or because we have destroyed the rivets after sanding and filling parts.
These sets of rivet-making tools allow you to create perfect lines of rivets, especially if you use a scribing guide.
Available in several diameters to allow for different separations between rivets.

We have to prepare each shipment individually as they are ordered, so allow it in 3-4 weeks to arrive in the USA/Canada (to be safe) and 3-6 weeks rest of the world, though they are usually delivered much faster.
