Review on Stacking Ring Toy - Stacks of Circles for STEM Learning, 9 Piece Set, Multi, Age 6+ Months by Peter Nobles

I love the versatility of this toy, especially compared to the traditional ring stacker. Black and white rings can be used on newborn days to show off contrasting patterns to your baby. A ring can be used as a rattle. All rings can be used to explore textures and teething. The only thing I would like to improve is that the holes in some loops are larger so that the toy can be used as a ring toss in later years and the material used is not plastic.
