Modern Style End Grain Cutting Board: 12" L x 10.25" W x 1.25" thickness is custom made from white oak, maple, mahogany, purpleheart, walnut, padauk and zebrawood.  It is applied with food grade beeswax conditioner. 
 
Those colors are NOT dyes or stains; they are exotic hardwoods from Brazil, South America and Africa. Others are from Appalachian in the northeast states. 
 
End grain board is also the most durable because of its' self-healing feature. Its' fibrous cell structure allows the board to spring back into shape after cuts and scratches.
