Promaster 4578 72mm スナップオンレンズキャップ

Finally, a cap that actually stays clipped on instead of falling off the first time I pull my camera out. The 72mm size is a perfect snug fit on my favorite lens without being impossible to remove.

Exactly the right fit for my 72mm lens—snaps on securely and stays put in my bag. I like that it doesn't have a flimsy feeling like some of the cheaper ones I've tried.

It does what it’s supposed to—snaps on and off without much fuss—but I wish it felt a little sturdier when handling it. For a 72mm cap, it’s fine, though I can’t say I’m blown away.
