These wooden blocks look like the ones kids have played with for years except that they are not cubes but flat blocks with magnets on the back. They are about 1.25" square and about .25" thick. You can use them as intended, as magnets, or you can use them for making something great! Perfect for child themed art. There are 40 blocks here, at least one for every letter of the alphabet. Use them in a collage, frame a child's picture, etc.
