A basic toy made even better in wood.  Your child will enjoy years of stacking, nesting, sorting, putting things in and taking things out of these colorful cups from Grimm's Spiel & Holz Design.  Later on, these can be great desk organizers.  Rounded edges and individually hand dipped in water based non-toxic stains.  Largest cup is 3 1/2" in diameter.  Linden.  Germany
