If you are seeking premium, American made wooden building blocks, these domestic toy blocks made of Rock Maple will last for generations. Blocks don't work very well unless they are cut according to the same standard.  These basic Unit blocks are 1.375 by 2.75 by 5.5 and all shapes: triangles, arches, planks, ramps, are an exact fraction or multiple of this size.  This is the generally accepted scale for schools, preschools, and kindergartens.  There is no other "correct" scale.  If blocks aren's this scale they may be playable, but they will not fit with blocks from other sets.  Blocks come in other sizes, but these hefty blocks are the standard in school settings.  These blocks are not coated with chemicals or oils. You can buy these wooden building blocks with the assurance that they are safe, that they will last forever, that they will integrate well with school sized blocks from times gone by, and that you can buy more of them.  Read Technical Details abut Wood Blocks (click here).
