Promaster Universal Cap Leash

The sticky pad method works great on my older cap that doesn't have a hole—holds firm even in my bag. It's nice having two ways to attach so I can switch caps without buying a whole new leash.

The sticky pad on this leash is surprisingly strong; I've had it on my lens cap for a week with no peeling. Having two mounting methods is handy since one of my caps lacks a leash hole. It finally keeps that cap from rolling off my table every time I set it down.

I was a little skeptical about the sticky pad holding up, but after a few weeks it's still firmly attached to my lens cap. The two mounting options really do make it universal, which is handy when switching between lenses.
