This little box saves you a LOT of time lacing wheels, and we use them religiously in our workshop. 

Just dump your spoke nipples in the box, lightly shake it so the heads are all facing up, and then use a tool like the EVT Mulfinger Nipple Loading Tool to pick out the nipple and thread it onto the spoke.

Paired with the Shuffle Box, using loading tools like the Mulfinger is now an easy one-handed operation!
