Grimm's sloping blocks

A tricky building set with different tilted blocks. Only the matching colours will complete a rectangle. All 6 blocks within one shade of colour (blue/red/green/yellow and purple) have the same tilt angle and therefore will also complete a rectangle. By building and playing with the uneven blocks, children develop fine motor skills and spatial thinking skills. 5+ 30 buiding blocks in a wooden frame. frame length 31cm, single blocks 6cm thickness. limewood with non-toxic, water based color stain and plant based finish made in Bosnia *this will incur a shipping charge of $15.95
