@jgreen19: The Vinyl Storage Solutions outer sleeves are fantastic, aren’t they? I recently put all my LP’s in various models of Michael’s sleeves: 2mil resealable double pocket with 2mil multi-purpose on gatefold covers, two 2mil resealable double pocket on gatefold double LP’s, 4mil resealable double pocket on thin-jacket UK LP's (including 60’s Beatles, etc.), 3mil single pocket with flap on some LP’s, 3mil no flap on sonically mediocre LP’s and 12" 45’s. It took a week to sleeve them all, but now I just have to do LP’s as they come in.
The VSS inner sleeves are real nice too: just like the MoFi, but thicker: offered in both 3mil and 4mil, the MoFi being 2mil.
