New FAVOLINK Waist Shaper XS Yui Yasui

New and unused.

Size XS

This is Yuli Yasui's waist shaper.

I have used the beltless, single, double, and RV types, and while the beltless and single/double types are more for beginners in terms of size and offer a gentler tightness than the RV, they may not be suitable for those who prefer a stronger tightening sensation.
However, I believe they are suitable for those who want to work on aligning their ribs.
This is just my personal opinion, for your reference.

Please feel free to comment if you have any questions.
