I am not 100% certain but, I think this is the same product I bought
several months ago due to the price.
The back side of it was backed with paper.
I purchased it as backer material for intarsia projects so, it worked
just fine for the intended purpose.

P.s. Just for comparison purposes, I also bought some
UltraPly by Moreland Company and it was terrible!
It was extremely cheap so, I thought I'd try it for fretwork. It has a lot of voids and splinters terribly.
The info they have on their web-site says you can
score it with a utility knife and snap it but, it will just delaminate
and splinter.
If you see this on sale, save yourself some aggravation and money.
