1L square bottle

Seems to be high quality and durable. I would definitely buy these again if needed.

I've tried 3 different brand/styles of bottles for my development chemicals. These are now my main one and I'm switching over to use this bottle exclusively. They are air and liquid tight. I put all my chems in a plastic tote and the square bottle fits in better than a bunch of round bottles. Paired up with a label maker I already have it's perfect to keep many various chems handy for different situations and film types. I'm upto owning 12 of these now. Be sure to label them well. And if you have waterproof multi colored tape on top you can easily identify sets for all your dev processes (C-41, B&W, ECN-2, E-6).

It's a solid product that does exactly what it says on the tin: It's three 1000mL bottles that are perfect for darkroom chemistry. A neat feature is that the bottlecaps "seal" on when you first use them, meaning the little plastic ring bites on like a water bottle cap, so you can know if the bottle you're opening is one you've used before or not.

Good containers, but the caps were all black, not colored like they were in the pictures

thus far, no problems with the c-41 chemicals I am using. I have to use some glass marbles to remove the little airspace at the top to prevent chemicals from going bad prematurely. seals up air tight. they come with a tamper ring (i guess that's what it's called) like milk jugs that once you put the top on for the first time, it breaks off so you know it's been opened. this was of no concern to me but seems like it could be a nice feature to have on some thing like this.

worked as they should

Two of the three bottles seal quite nicely, namely the bottles I use for C-41 Blix and photo-flo. However, the red bottle from my batch that I use to hold C-41 developer has a bad seal. The lid just keeps spinning and feels like it never snugs up properly.

Been used to store mixed b&w chemicals and I have had zero issues

Great quality product perfect for my needs

These bottles are excellent for storing chemistry. The plastic feels thick and durable, the caps seal well, and they hold up nicely over time without leaking or deforming. We use them regularly in a working environment and they’ve been very reliable. Great quality and exactly what we needed for safe chemical storage.

Exactly what I ordered.

Excellent for darkroom chemicals, black plastic keeps the sun out and different lid colours for easy identification. Also come with a series of sticky labels to customise. The material allows temperature transfer from the waterbath. Good value for the prive and square ones function well together in a smaller space.
