I brought alot of cubes to the Mossouri Open. Someones little brother thought that every cube was mine and put a TON of them in my backpack where all my cubes were. I went through at the end to see if I had all my stuff only to find 10 extras.
Do you have one that's a hybrid of an old storebought core and type A pieces? The core is missing the yellow sticker, and the centerpieces are flat on the inside instead of rounded. It's been missing for a while, and I'm pretty sure it disappeared at MO open.
