I recently received my order of 100 of the Guardhouse 30 Pkt Archival Notebook Pgs for 1.5 x 1.5 Coin Flips and they are outstanding. I actually do not use them for coins, but rather guitar picks. They are perfect for most guitar picks in the 1.5 x1.5 size and hold the picks in place very well. Plus, the fact that they are archival quality really sealed the deal for me because these pages will prevent deterioration that sometimes takes place in vinyl and PVC pages that are not archival. I have no doubt that I will continue to order these pages from Coin Supply Express. They are the best!
