Strict Leather プレミアムロッキングカフス

The weight alone tells you these are serious—over 10 ounces of metal and leather. The locking buckle works perfectly whether you use the actual lock or just the buckle itself.

I was worried they'd feel flimsy for the price, but at over 10 ounces these things have real heft to them. The buckle works fine without the lock too, which is handy when I don't want to bother with the key.

The locking buckles are genuinely solid and I like that you can use them with or without the lock depending on the situation. Ten ounces doesn't sound like much until you have them on, and that heaviness is exactly what I wanted.
