NIIMBOT Labels, 2 Rolls Refill Thermal Label for Label Maker B1/B21/B21Pro/B3S/B31/K3, Waterproof, Oil-Proof and Tear-Proof Sticker Labels, 0.4'' x 0.8''x4 (10x20mmx4) White

Perfect label size for 3mL vials. They are durable, and the corners are sharp. The adhesive is strong and I haven’t had any issues with applying them onto vials. They look great and are easy to use in my NIIMBOT B1 Pro.

What can I say? These labels fit well in the printer and print equally well. What's not to like? Drop the roll in, hold the loose end near the tear-off bar and close the lid. The printer does the rest. Easy peazy! If you have a Niimbot printer, you will be happy too!

These labels work perfectly with my NIIMBOT printer. The print quality is clear and easy to read, and they stick well without peeling off. I like that they feel durable and don’t smudge easily. They’re also really versatile—I’ve used them for organizing everything from pantry items to storage bins and office supplies. Overall, a reliable refill option that I’d buy again!

Great quality good amount of print paper - no smudge or ripping when peeling off

Works for my needs

These are the best. I've also discovered that they make a "write on" Matte version. I'm happy with these, and yes you can't write on them, they're pretty much impervious to people marking them, so they make great labels because nobody can visually tamper with them... just another "something" to consider.

Love these labels for my vintage booth items. They are the perfect size and stick great, without getting too stuck!

Sturdy unit that performs well once you learn how to use and format the labels. Labels are also high quality. To some they might want larger labels but this one is just right for our home use.
