Great visibility

Very easy to read in the dark. I deducted one star because I wish they came in more shape variations, but the rectangular ones work fine.

No fogging issues

I was worried about the fluorescence affecting my Ilford paper, but tested them thoroughly and had zero exposure issues. Highly recommended.

Good quality adhesive

Sticks well to plastic trays and cardboard boxes. Removed one easily without leaving gunk behind when I made a mistake.

Essential darkroom gear

Marked all my chemical bottles and paper boxes. The glow is strong enough to see from across the room when the white lights are off.

Perfect for my wet lab

These stickers are incredibly bright under safelight conditions without fogging my paper. The adhesive holds well even in humid developing areas.

Bright and safe

Exactly what I needed for organizing my student darkroom. The non-exposing spectrum claim is accurate based on my tests.

5 FAQ

Q: Do these glow in total darkness or only under safelight?

A: They are fluorescent, meaning they reflect and amplify safelight wavelengths to appear bright; they do not phosphoresce (glow) in total pitch darkness without a light source.

Q: Will the adhesive fail if splashed with developer?

A: The adhesive is water and chemical resistant, making it suitable for environments where occasional splashes occur, though direct prolonged soaking is not recommended.

Q: What is the shelf life of the adhesive?

A: When stored in a cool, dry place away from direct sunlight, the adhesive remains effective for up to 3 years from the date of manufacture.

Q: Can I write on these labels with a marker?

A: Absolutely. The surface accepts permanent markers and grease pencils well, allowing you to customize warnings or instructions.

Q: Are these safe to use with orthochromatic film?

A: Yes, these labels are designed to be safe under red and amber safelights typically used for orthochromatic materials, but always test with your specific lighting setup first.
