Good quality product
Whether purchasing them with the traveler's notebooks or just getting them separately, these notebooks are lovely. Very minimalistic outer appearance, with the tan leather piece in the corner giving it a lovely character. I bought them while on the hunt for fountain pen friendly paper, and it fits the bill quite well! Using slightly textured, heavy 100GSM paper, there was almost zero bleed through to the opposite side, with very little ghosting. The ink is readily absorbed into the page, which is great if you're a fast writer or a leftie. As long as you don't expect Tomoe River levels of shimmer and sheen with your favourite Shimmertastic or J. Herbin 1670 inks, this notebook will take everything else you throw at it and more!
Although it might look slightly expensive for an A6 notebook, the quality of the book and pages, as well as the nifty leather corner, speak for itself! I personally love the dot-grids, but ruled and blank versions are also available. If you're a fountain pen user, GET THESE!
