I bought 2 rolls and loaded one into my Dymo printer, and after trying a test print, I knew right away these were knock-offs

Use the mfg labels because the cheap knock offs jam,

I ordered again in August 2018 and received knock offs

OR MORE plus your time to try to remove them from the workings of the printer - these are not the cheap knock offs either

Adheres well and doesn't jam machine like cheap knock offs do.
