What is GOOPER Tecnology

Our patented magnetic strips are deceptively simple in look,
yet sophisticated in design, using fully encapsulated neodymium magnets embedded in a variety of polymers.

The technology is based on simple science
when you place two GOOPER magnetic
strips next to each other and let go,
they (click)smack together to create an instant, waterproof seal.
