I bought this for my daughter who asked for them to help get into shape and when she said mom what did you do with the bands i thought she was joking. I then realized they weren't there and felt foolish that i had bought an empty box. The people in the store where i bought them were all spread thin since it looked like they were going out of business so i decided not to bring the empty box back. She still doesn't have her bands but i think walmart down the street sells them
I bought several pairs of these. They are fantastic. Gave some as christmas gifts. Provides an easy and fast way to get some stretch resistance.
