These are end wrap papers that you use to protect the ends of your hair from heat damage when getting it permed. It also turns out that the papers work quite well as blotting papers. The best part? You get 1000 sheets for $2.00. You can purchase this at Sally Beauty Supply.
I will say that it's not in the most travel friendly packaging but you can easily remove a few sheets and put them in your wallet or repurpose packaging from other blotting tissues you've owned. I'd say that it isn't as oil absorbent as I'd like for it to be (you do need to apply a little pressure to blot off the shine) but for $2.00, it's a good alternative to more expensive blotting papers.
Hope this helps!
