Indonesian Handcuffs and Thumbcuffs

 This is an unusual swing through ratcheting modern design from Indonesia. I don't know anything else about them. Another collector has mentioned them before but I haven't been able to find that yet. I'm not sure if they double lock. There is no swivel. 

The surface has an interesting pattern. The starting bid is $0.99 and both restraints come with two keys. 

UPDATE: SOLD for $488 after 26 bids. Very unique set of restraints.
