Seems to be excellent quality! The paper is quite thin, being a lighter wight at 90gsm, and yet I've even been able to do quick marker sketches on it without any noticeable bleed-through (your results will almost certainly vary depending on your markers and how much you lay down.)
The paper has a nice feel and I really like the warm tone. I'm binding mine into a smaller custom sketchbook, and doing a Sashiko cover for it using supplies also from The Ribbon Rose.
