This set of 12 Grapat perpetual calendar rings  adds an extra dimension to your Grapat calendar.  Mark the current month with a ring, or put rings onto all the monthly nins, and add the current month with nin onto the middle cup. 

You can also use the calendar rings without the Grapat perpetual calendar for sorting, counting, stacking and threading.  Combine with Grapat Nins® or other wooden peg dolls or block sets or use them on a tinker tray or for loose parts play.  These wooden toy rings make a great Montessori material and are really versatile.

Recommended for 10+ months. Diameter 4.7cm.  Handmade using natural sustainable wood and water based stain.
