These blocks are ideal for open ended play: Through the irregular shapes of the blocks the children are inspired to use the blocks as car, ship, iron or to build up a landscape. Due to the non-varnished surface, young children are able to stack the blocks easily and the included net bag makes it easy to tidy up. The blocks are sanded down by hand and therefore have no sharp edges or corners. Each of our Waldorf Blocks is unique - shapes and sizes will vary. 15 blocks in net bag. Materials: lime wood, non-toxic water based color stain. Size: ca. 6-8cm.
