[FishDish]

I have been searching for original 7x7s, older big cubes and such. Just trying to enlarge my collection.
Lefun 7x7
Moyu Aofu (pillowed, pink stickerless) 7x7
MF7 (stickerless)
YJ Ruifu 7x7
YJ Yufu (stickerless, nonmagnetic) 7x7
YJ (pillowed) 7x7
LanLan 7x7

​

I would also be interested in purchasing or trading for the original YJ Yushi and Guanshi 6x6s, or the moyu weishi 6x6.
