The only labels I buy again and again.
Size: 1.97'' x 1.18''-White, Color: White
The only labels I use for my thermal printer. Print quality is always perfect. The quality of the sticker is great! Super easy to use just drop them in. Easy to store and organize. Not the cheapest but they don’t stick to my products when removing but they stay on nicely until removal is needed.

The Hobby Crafter Review: Stick well, clear print, durable, accurate alignment
See below the way I choose the star rating.
First I want to say that I am still mad, that the NIIMBOT printer only accepts original NIIMBOT labels, which come at a VERY limited choice, are pricey, and often not even available on Amazon. That being said, those labels work very well, the print is crisp, even the small letters (see picture, the small letters are 1/16"). The ink does not come off, even when rubbed with greasy fingers.
I am not able to remove them easily, the adhesion is very good. All prints are centered, even when printing multiple. They align very well in the printer. Which is to be expected at that price!
I will buy them again once they are available, because I have no choice, but also because the quality is very good.
Star Rating:
***** Exceeds expectations and is better than thought
**** Meets expectations and would buy again
***Some minor flaws but ok for the price, would not buy again
** Terrible and I only kept it when the price is right or because of the lack of better alternative
*Returned the item because it doesn't work as advertised, is broken, or quality is extremely poor

20 X 40mm vial labels
Size: 1.6“ X 0.8"-White, Color: White
Works perfectly. Make sure when you’re buying labels that you don’t buy M1/M2 labels unless you have the M1/M2. You need direct transfer unless you have the M series with the fancy color cartridges etc. The “fancy” labels won’t work on normal thermal printers, they need the color cartridges to show up.
Anyway this is the 20mm X 40mm size. Perfect for vials. Works in many other non-branded machines.
