Thank you for looking! (*´人`*) I bought this unused unit on Mercari about six months ago because my friends and the staff at the sports club I go to liked it and used it, and I felt I wasn't stretching enough after exercising. However, I only tried it once and it's been sitting in the closet ever since. No smokers in the family. I will ship it via anonymous delivery. I will wrap it in bubble wrap and package it in a plastic bag, etc. Below is the description from when I purchased it: ★Made by a fitness club★ ★Qfitter Pro★ This is a unique stretching tool with two rows of balls. By using it while lying on your back, the balls arranged in two rows along your spine press on the muscles of your back, relieving muscle stiffness. Furthermore, the balls fit into the space between your shoulder blades, allowing you to stretch while spreading your shoulder blades left and right. It can also be connected vertically and horizontally, and can be folded, rolled up, wrapped, and flexibly shaped, allowing for various stretches and exercises. It can be used on the floor or on a chair, making it convenient for multitasking. ・Body: Polyester, PVC ・Balls: EVA 【Size】 ・Approx. 52cm long x 22cm wide x 7cm high (1 piece) ＜When connected vertically＞ ・Approx. 99cm long x 22cm wide x 7cm high ＜When connected horizontally＞ ・Approx. 52cm long x 40cm wide x 7cm high
