These are Genuine Kirby Straps. Simply replace your own belt on your vacuum cleaner. Love that there are 3 in the pack because after only 4 days my daughter pulled the rope into the kirby and burned her way through another strap (not the product's fault but she thought it was just pushing it away, instead of sucking). it is above). It's nice to always have at least one extra vacuum on hand, especially if your kids are helping out with the vacuuming.
