This is a listing for a set of 5 individual rings for Plus10. There is one of each of the 5 colors, but some of the color has faded due to age. The yellow and wooden ones are difficult to distinguish. Please consider this before purchasing. If you are okay with this condition, I have multiple of each, so please feel free to inquire. - Colors: Red, Green, Blue, Yellow, Wood - Shape: Circular - Material: Wood - Purpose: Educational Toy
