***price is firm*** I have a number of these cases available from an excess close out. All new in boxes. The exterior of the cases are 18" L x 12" H x 8" W, approximately 3mm thick pressboard walls, aluminum sheeting exterior and includes locks and keys. You can easily put about 30 lbs in one of these cases without any issue, I haven't tested beyond that but suspect you can put far more in it.
