These fun  backpacks with an orange stripe are made out  of the protective scaffolding netting that covers the buildings under construction in NYC. I use the ends of the rolls of this netting that would otherwise end up in landfills. They are durable and waterproof closes with a magnetic snap. Comes in  two sizes, small or large. 

Small backpack measures 9" across ,11" high and is 2" wide.   

large backpack measures 10" across 12"high and 2" wide
