These ultra pro sleeves are very practical: - There are multiple holes to hang in workbooks 2,3 or 4 holes choice - No one puts bp pokemon card, approximately maximum 5 / box -by against, and I take off a star for that, one of the boxes on 9 (the lower left) is more fragile, and sometimes a little off to the left side when you put more cards. But it's really to quibble ... Overall, I am very happy with my purchase. I put the bags in a classic archive office filing cabinet, 2 holes.
