How to label CD/DVD wallets?

Do you keep your discs in wallets? I do and I have several 216+ size wallets. I’m having trouble labeling them. I’ve tried a casio labeler, a brother labeler, neither of those would stick so then I tried putting scotch and or packaging tape on top. Nothing is working for me. Some are nylon but most are faux leather. Suggestions?

I use a White-Out pen to label my Commercial DVDs, no reason to believe it wouldn’t work on wallets. If you don’t want to handwrite labels you could use the bottled white out to paint a patch that the printed labels would stick to.

Not sure the whiteout “underlayer” would work as a good glue…
