I don't know what irritates me more. I bought a dozen or so new boxes (3600,etc) the other day. Watching basketball I decided I would start to change bad boxes with the new ones. Taking apart the plastic dividers is a pain in the rear! I've got plastic tabs flying around the cave, cut myself once and I'm on box 3. Any secrets other then my razor knife ? And no, these aren't the $30.00 ones that look like a Pelican case.
