How old is your friend...how did u get all the cubes to u from various brands like gan and moyu cause my friend wants to open up a cube store too!
Qimeng + would probably work well. Not very economical to use over 30 of them though.
Yep, I think there is also a factor in the surface of the cube, meilongs are polished so smooth and a bit slippery, I suspect even QiYi Warrior S's would work better. QiMeng Plus's would probably work even better but I suspect I would need a ladder and a far higher ceiling!Qimeng + would probably work well. Not very economical to use over 30 of them though.
