Colorful Hula Hoops, 5 Colors, Set of 20

This is a set of 20 colorful plastic hula hoops.
I bought these after seeing them used at my child's sports class to help them easily learn games like hopscotch.
I think they can also be used for ring toss games.

The rings are about 20cm in diameter, which is a perfect fit for the feet of small children.
My child enjoyed playing with them indoors during the colder months.

Thank you for looking.
