This notebook ticks all the boxes for me. Wirebound, so it lies flat and folds over, and twin ring configuration to keep it from snagging on anything. The covers are very stiff, which means you can write in the notebook easily even if you don't have a desk or clipboard. The perforated paper detaches easily and without tearing. And the paper is glorious if you're a fountain pen addict like me--bright white, smooth, no feathering or bleed, and showcases shading and sheen really well. It's up there with Clairefontaine, IMO. I find the cost to be very fair as well for the quality of this notebook.
