Great for 3ml custom peptide vials!
Ordered the Laser Silver labels for our 3ml custom peptide vials in the lab. The stock film is highly resilient—completely survived the -20°C standard freezer storage without any edge curling or fading from chemical smudges. The M2 thermal transfer system is an absolute lifesaver for small-batch clinical test prep.

Perfect for our laboratory workflows
Flawless adhesion on micro-vials. We required specialized medical vial labeling for our biological samples, and this package delivered exactly what we needed. The text is crisp and entirely chemical-proof against standard lab alcohol smudging. Will definitely reorder the replacement rolls from officekoala!

Excellent B2B support and quick delivery
The automatic tiered bulk pricing is great for startups. We use the holographic and matte options for our formulation vials. Adheres perfectly without peeling under standard refrigeration. Plus, it shipped out within 24 hours from their CA warehouse. Solid purchase.
