7 Layer Snow Globe Decoration. Layers 1-5 stack on top of each other to create a Christmas scene. Layer 6 is the base that layers 1-5 will go into. Layer 7 snaps onto the front of the base to keep layers 1-5 in. A dab of glue on layer 7 will help if loose. You can scale down 0.1% if layer 7 is too tight, but it should be a good snug fit.
