Grimms 6 Rainbow Wooden Balls *ETA Oct/Nov*
These rainbow wooden balls are meant to supplement other products, most notably the Grimm’s Rainbows to create a fun ball and marble run! (See pic for ideas) They are also good for developing colour sorting skills, of course.
Made from maple wood and finished with a non-toxic water based color stain. The diameter of each ball is 4.5cm.
