I accidentally came across the opportunity to make a hybrid. My girlfriend has an old genuine Rubik's brand but its a promotional cube of some sort so its a little different to a regular Rubik's brand. The writing has rubbed off of the white face now so it looks normal. But I was solving it and dropped it and the core shattered and I was conveniently left with all the pieces and all the centercaps had come off. I bought DaYan hardware and core and put the Rubik's pieces on that. Its a fantastic cube haha, fast, smooth and cuts better than my guhong I was extremely suprised!
