8 complex pcs & 2 balls that are internal to the puzzle. Extraordinarily challenging. Even the disassembly will be beyond the capability of all but the most skilled puzzlers. It is a sequential locking cube that has the compounded impact of the internal marbles preventing disassembly until maneuvered properly. This is in my opinion our MOST difficult puzzle. It is difficult for me to imagine solving this without use of the provided instructions. An exclusive Creative Crafthouse copyrighted puzzle from our shop. Designed for us by Ramu Kaminoff in 2008. The Ramube measures about 4 x 4 x 4" Congratulations to Theresa Machemer. A 15 year old from New Hampshire for being an Etsy first & solving this incredibly challenging puzzle!!
