I'm kinda the reverse of DED...usually toss a box when it gets below half full...
I have one large tupperdor (24" x 17" x 8" --12 gallon?) with 6 snap lid holding boxes -- maybe 12-15 in it now, one shelf of a three shelf end table humidor devoted to boxes, many with a variety of stuff that I write on an adhesive label to keep track... the other two shelves are loaded with trays of singles, as well as the top pull out drawer...
three table top humidors, one 25 count, one 100 count and one 250 count, all filled with singles
four smaller two gallon snap lid tupperdors filled with singles...
explains why I leave the cello on...
