This is a scale stick to be used for comparative photographs of miniatures. It is designed to fit neatly beside the base of most miniatures, with pointers extending outward from each of the numbered demarkations. The stick is marked at common values used for measuring miniatures at 6mm, 15mm, 25mm, 28mm, 30mm, 35mm and 40mm, with the last pointer at 45mm not numbered. It is cast in lead-free pewter and supplied unpainted.
The one I have been using is simply spray-painted black, with the raised numbers lightly sanded to remove the paint.
Though some variation in length may occur due to the soft tooling of spin-cast molds, we have taken the greatest care to make sure the device is accurate within one half of one millimeter from 0mm to 45mm.
The idea is to simply place this tool beside a miniature when taking photos, to let others get a pretty good estimation of the actual size of the miniature in the photo. You can see this in use in most of the photos in my store.
