We have been using these Dymo labels in our business for several years. I have checked intermittently over the years to see if I can get them at a better price from other providers. Every time, Label City has had the best value!

Great product used daily in our business.

Perfect size for warehouse use

We've been using this label for many years, 100's of rolls. Perfect for all of our product labeling and it never fails. The adhesive is awesome. I never used these on disks but hear me out. Back in THE DAY, 3.5" labels were mostly removeable type and would not hold well to the disk, corners would peel up and being OCD, that just won't do. I was more of I want this sucker to be permanent sort of guy...if I need to reuse this disk, I'm slapping on another label. It's 1992, I just downloaded Win3.1 off a pirate BBS, it took a week and I for sure am never going to be re-using these disks. Ya know? So anyway....the point is these labels are Niiiice, like long niiiiiiiiiiice. I don't play around.
