This is a large shipping case I designed and had built by Badger Case in Wisconsin. Used to ship my artwork across country or carry artwork to my shows. The outside walls are a hard but lightweight material, the inside has 1" dense foam, soft but strong. The outside dimensions are 54" long, 15" wide and 44" tall. Inside dimensions are 51" long, 12" wide and 40" tall. The lid fastens with three units, hands on either end at on top. The corners are rounded like musician cases so they slide easily and protect the surfaces during sliding over pavement.
Price is $500. Local pickup here in Bloomington. Payment can be credit card or cash. I can provide you an invoice for the purchase.
