A containment vessel formed from at least two rigid panels placed in a parallel plane having a spacer positioned between the panels wherein a containment area is formed along an upper surface of the spacer and inner surface of the rigid panels. The spacer can be formed into any shape with a distal end and proximal end of the spacer forming an inlet to the containment area. The containment vessel employs a reusable securement fastener allowing for the disassembly of the panels and replacement or reshaping of the spacer to form different shaped containment areas. The containment vessel can be pre-shaped or fixed.
