Firstcall Chemical 琥珀色玻璃粉末罐 - 30ml

I've been mixing my own developer batches and these 30ml jars are perfect for one-shot testing, the amber glass keeps everything light-safe and the screw lid seals tight enough that I haven't smelled a single chemical leak in three weeks of storage.

The amber glass is thick and feels really solid in the hand, and the seal on this 30ml jar is tight enough that I'm confident my fixer won't evaporate. It's a small detail, but the smooth finish makes it easy to grip even with wet gloves on during tray processing.

Finally, a jar that doesn't react with my fixer—the amber glass keeps everything stable and the 30ml size is perfect for small batches. I've left mixed chemicals in here for weeks and they're still just as potent as day one.
