European 8 in 2 out of mild steel
A small sheet of Kingsmail or European 8 in 2, currently containing 1518 rings made out of 16g mild steel, wound on a 1/2 inch mandrel. The rings have an AR of 8.12 which is a bit too big by most standards for armour but they are the only rings I had at the time. This sheet is only 18 inches wide by 9 inches tall but it already weighs in at 2.75lbs or 1.25kg.

E8-2 makes for a thick and heavy sheet of maille.
