They came off too easily and the ink smeared.

The second time the ink smeared right off on my finger and a tissue with light pressure pretty much made the words unreadable

I tried two different black sharpies and the ink smears right off the labels.

I had some issues with the ink smearing even after waiting a reasonable amount of time (even 24 hours for one label) before adhering it to the fabric lunch box

Also, after pleanty of washings, the stickers are still intact and I can read them as clear as when I wrote on them!
