Last night I purchased a notebook at Borders that was manufactured by Miquelrius but carries the Paperchase label on the cover. Is this a Borders branding? They only had a few styles but maybe there will be a better selection in the future if there is such a partnership for Miquelrius.

Yes, I saw the same thing the other day. I bought a lovely large red spiral notebook that had the Miquelrius logo at the bottom of each page, and the colored lining on the edges, but on the back it said Paperchase.

I bought a grid lined PaperChase pad at Borders. Bleeds through and gave it away.
