So my chubby mom was watching a Korean Drama when she came across this little exercise device. After watching the drama, she decided to ask me to buy one for her. The problem is, I live in the States and have never came across these type of exercise equipment before. So I decided to look online and see if I could buy one from there. After doing quite a bit of googling, I found a few of these items on Alibaba and Aliexpress. But since I have never brought any products from those two sites before, I am having trouble trusting the seller on it. Does anyone know the name or official retail site of the device or a trustworthy site I can buy it from, I would love to know it. Otherwise, thanks for reading!
