High Density PolyEthylene -- the same material used in commercial kitchens -- will not absorb moisture or odors, will not harbor bacteria, and does not stain.   

Acoustic or electric-- whatever mood the chef is in-- let the music begin!   Drip-groove around the perimeter of the guitar body and fret lines are easy-to-clean details.  1/2" thick material has the right amount of "heft" to it!  Handy hanger hole at the top.  Dishwasher safe, too.
