Another product that says it all in the name, well almost. 
These Brain Salt and Pepper Shakers are white ceramic, they also have a magnetic clasp to hold them together while sitting in the middle of the table. You wouldn't want to lose half your brain would you? 
Salt fits neatly in one half, and pepper in the other.

Oh and they are 6.0 x 8.0 x 5.2 cm..
