Q: Are these labels compatible with 3ml autoinjector pens?

A: Yes. Our 3ml labels are ultra-thin yet durable, designed to wrap securely around standard 3ml vials and cartridges without adding bulk that could interfere with autoinjector mechanisms.

Q: Can I write on the EXP and LOT sections?

A: Absolutely. While the labels are waterproof, we use a specialized top-coating that is compatible with fine-tip permanent markers, ensuring your handwritten batch data won’t smear.

Q: Will the ink fade in cold storage?

A: No. We use UV-cured inks and protective laminates that are specifically rated for cold-chain storage and refrigeration.
