Jobo 3300 薬品保管ボトルキット - 1L

I've been through a dozen chemistry sets in my darkroom and these are the first bottles that don't leak a drop when I shake the developer. The clear/white finish on four of them lets me gauge remaining volume at a glance while the two black ones keep my fixer safely in the dark. Solid, thick plastic

The white bottles let me see exactly how much chemistry I have left without lifting the cap, which saves time during a busy session. The seals on these feel reassuringly tight, no leaks at all so far.

The six-bottle set fits perfectly on my darkroom shelf, and the white plastic is opaque enough to keep chems protected from light. I especially like that the caps seal tightly without any leaking, even when I shake them to mix fresh developer.
