Yuil handcuffs are made by the Yuil Corporation in South Korea.  Founded in 1992 the company has gone from strength to strength. I stock the entire range of handcuffs and restraints and I reckon it is one of the best collections around.   Any weight saving for a busy law enforcement officer is a bonus and Yuil alluminium handcuffs really help in this area without sacrificing security.  Yuil now export to many countries including China, the Philippines, India and Venezuela to name just a few.  I now stock the well established range of 'K' series handcuffs.
