Handcuffs disposable Alcyon 5001 braded nylon cord

The handcuffs consist of a nylon strap attached at both ends and threaded through a ratchet with four holes. The strap is made of 8 braided threads with the following dimensions:
Length: 80cm
Width: 7mm
Thickness: 2mm
Weight: 11g

The ratchet is made of plastic material and has 4 holes through which the strap slides. The two central holes measure 8mm in length and 2,5mm in width, and the other two are 8mm long and 7mm wide. 
The ratchet allows smooth sliding of the handcuffs with minimal effort and quickly. It has angled teeth that allow the strap to pass only in the tightening direction. 

They are easy to carry, prevent infections and are impossible to break with teeth (you need a cutting tool to remove them).
