The threading on this lid is machined just right—no wobble, no jamming, just a solid seal every time. I've run a few rolls through and the light-tight fit gives me real peace of mind. It's clearly built to outlast the rest of my darkroom gear.

That lid clicks on with a reassuringly solid feel, and the build quality is exactly what you'd expect from a company with this kind of history. It's made my processing routine noticeably smoother.
