What is this rolling pin used for?

This rolling pin was in a box with some other vintage rolling pins that I purchased at an auction. This particular rolling pin was wrapped in paper, and I didn't even know what it looked like until the auction was over. It has four sections that all move independently of each other, and each section has dimples all around it. Each section has the name, "Magic" on it and says "pat. pending". Those are the only markings on it. The sections appear to be made of rubber. Does anyone know what this rolling pin was used for? Any information is greatly appreciated! Thank you!
