Peerless Model 730C Superlite Aluminum Handcuffs with extra long 8" nickel plated steel chain. The lightweight handcuff will be easier on your wrist when cuffed to a briefcase for long trips transporting extremely important items.
These cuffs are ultralight and very solidly built, the chain is the heaviest part. I'll be using these to transport expensive guitars in and out of seedy places and these will make sure they stay with me.
