Found in 2004, ACI Toys International Limited (ACI Toys) is a Hong Kong based developer and producer of original design, authentic scale historical and licensed action figures. Our renown products included main characters from the film Lord of the Rings: Fellowship of the Ring, partnership with Hong Kong designer Jason Siu; ACI Toys' own historical series, ranging from Greek Hoplite to Roman Legionary and Crusaders, as well as a licensed Samurai series based on famous Japanese illustrator Hiroyuki Suwahara.

​

ACI released 2 characters in 2015 and it is unclear if they will releases any further. Their figures were very high end and used quality materials. ACI was competing with ASMUS Toys for this market. Both releases were in 1/6th scale or 12" in height.

​

Both Aragorn and the Ringwraith were designed by Eamon O'Donahue. He also designed most of the Lord of the Rings figures for ASMUS Toys.
