Hello! Welcome to my page. My mother has difficulty going up and down stairs. She jumped at this simple stepper, but she couldn't use it well and hasn't used it in a while, so I'm selling it. It's stored in like-new condition! It seems to be good for dieting for young people, so I will give it to someone who can use it effectively. Please refer to the instruction manual in the 1st, 2nd, and 3rd photos for how to use it. *Please note that the instruction manual is not included. Also, the wavy lines in the photos are due to the photography. Please understand. I'm looking forward to your comments. THANK YOU❤️
