Cardboard is a great building material. As a kid I remember building forts, castles, etc with large cardboard boxes and duct tape. Mr McGroovy has designed a rivet an ingenious aid that helps attach cardboard pieces together into cool play structures i.e. castles, boats, trains, etc. These cardboard structures are attached together with these rivets and can take a good amount of abuse. Mr McGroovy was sure thinking with this simple yet great invention.
