This is an Advanced Duplicator Pack of PHX building blocks. They come in, 1x1,1x2,2x2,2x4,4x4. They are boxes and are completely hollow. This makes for amazingly easy building. Hopefully if I get enough positive feedback, I can make more. thanks for the help and keep the flaming, loving, and downloading COMING!
