This coaster set was featured in one of Professor Seelinger's story times... need I say more? I also heard it could prevent you from flunking Diff Eq, so take that as you will.
This coaster 4-pack includes one of each pictured design.
This ND Mechanical Engineering Coaster Set is crafted from birch, laser-engraved, and finished with our 5-step process. The coasters measure 3.5" x 3.5" and are packaged in a plastic sleeve and presented in a white gift box.
