Mega Bloks is a wonderful first building set for younger children (toddlers) because they are easier to "snap" together than the Lego Duplo brand. Please see photos as these are the exact blocks you will receive. Variety of sizes and colors, as you can see. The "towers" of blocks are 10 pieces each (except for 2 towers that are 9 blocks, somehow I lost a block on them!)...so that makes counting the total easier.
