The paper itself is ok, grammage 230g is not just super premium, but ok for the Photograph (with me with Canon Pixma iP 2700). The usual package size for the paper is the manufacturer website, incidentally, 20 sheets. The manufacturer sells the otherwise 290g in 10-sheet packages.
For 10 sheets of the required EUR 5.98 here are expensive arg at only 230g. Therefore, for an otherwise decent photographic paper having good printing only 3 stars.
(The life I can evaluate if the prints are only older, I should notice something, I will update the review)
