Czech Master Kits, known as CMK, is one of the prolific model companies out of the Czech Republic releasing full kits and aftermarket parts for aircraft, AFVs, ships, figures, and more.
This includes a series of brass chains which are listed as Fine (72nd scale), Medium (48th) and Coarse (35th). This review covers the Fine version of these products as I build mostly 1/72nd scale kits. What you get is a very nice chain in brass that is 30cm long (almost 12 inches). The links are 2mm long and 1.2mm wide. The quality is high. You can either use the chain at its full length or cut it into smaller sizes for different uses.
