This is a hand extension designed for use with the Pilates chair equipment. Most Pilates brands are made overseas, and for Japanese people, there may be exercises that are difficult to perform due to shorter arms, and often there are no support tools available, forcing them to give up. I've created this tool (handmade, in other words) to allow those people to exercise safely. I'm not sure how much demand there is, so I've only made one set. To be honest, it was more difficult than I expected, so I probably won't make any more... I will not be offering a discount. (It took a lot of time and money to make...)
