Recently we received a package, and instead of styrofoam popcorns exploding out and clinging to everything, we were greeted with a new solution. They are called ExpandOS and are an inventive response to recyclable shipping. they are biodegradable, from post-industrial waste and are reusable. These lightweight cardboard pyramids latch together and create a web of support and according to a testimonial you can drop eggs off a 20-foot balcony and these little guys will protect them. It is innovations like this that can make a difference and we commend this company and hope that we receive more packages with these and please, please no more Styrofoam.
